# to choose a Pin to PAP distance<br />
<br />
<br />
<br />
.<br />
<br />
==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Understanding Sums of the <u>Benchmark Range</u> ''''' (neccessary for calculations)''=== <br />
The Benchmark Range is necessary for adjusting other layouts off from the benchmark layout so the bowler will not have to change their specs when playing various conditions (Long & Strong layout/Control layout/Mid-lane layout/Totally Strong layout/ etc). <br />
<br />
'''''Total sums (drilling angle + VAL angle) determines the length of ball motion until the roll phase.''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />
<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
====Example====<br />
Sweet spot of <u>100º sums</u> using '''(± 20º)''' for this example.<br />
<br />
For dry or short oil patterns to increase length, use <u>120º sums</u>. <br />
*Use a high ratio for ''<u>long and strong layouts</u>''... ''(longer and quicker reaction to the dry...more of a skid /snap ball motion)''.<br />
*Use a low ratio for ''<u>control layouts</u>''...''(slower/smoother reaction to the dry)''<br />
<br />
For oily or longer patterns to decrease length, use <u>80º sums</u>. ''(utilizing ratios to achieve the desired break shape)<br />
*Use a high ratio for ''<u>Totally Strong Layouts</u>''... ''(defined/sharp motion...quicker reaction to the dry)''<br />
*Use a low ratio for ''<u>mid-lane layouts</u>''...''(earlier/slower reaction to the dry...smoother & more continuous ball motion.)''<br />
<br />
.<br />
<br />
==Find Your Benchmark Ratio ''(by primarily analyzing tilt and rotation)''==<br />
'''''This is necessary to accurately calculate the drilling angle and the val angle individually.'''''<br />
<br />
For examples on how to do the math, see ''[[Dual_Angle_Ratio_Guide#Simple Math Examples|simple math examples]]''.<br />
<br />
<br />
==='''<u>Step #4</u>-Find The Initial Ratio From Axis Tilt'''===<br />
The middle column (''initial ratio benchmark range'') gives approximate ratios for bowlers with ''speed/revs = matched + normal rotation.''<br />
<br />
Please note: when creating the chart we used 50º to 55º as normal axis rotation. (45º is slightly low and 60º is slightly high)<br />
<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º (especially when accompanied by high rotation) use this [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]].<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º accompanied by low rotation use the chart below:<br />
*For low ''[[axis_tilt|axis tilt]]'' with very low revs use the chart below (even with high rotation):<br />
''Chart created by Athery''<br />
[[File:Ratiochart.png]]<br />
<br />
'''Special notes for axis tilt below 7º:'''<br />
With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />
Here is a [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]] on how to adjust Athery's chart, especially when low tilt is accompanied by high rotation.<br />
<br />
==='''<u>Step #5</u> - Adjust the Initial Ratio '''''(from Step #4 If bowler has high or low rotation)''===<br />
'''Amount of adjustment necessary depends on the relationship between rotation and ball speed.'''<br />
*High rotation and/or high rotation accentuated with speed dominance = ''decreased ratios'' (use boxes further right on the chart)<br />
*Low rotation and/or low rotation accentuated with rev dominance = ''increased ratios'' (use boxes further left on the chart)<br />
<br />
==='''<u>Step #6</u> - Find The Ratio ''<u>Range</u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />
<br />
The maximum ratio and minimum ratio (drill angle and val angle) which should be utilized with your personal sweet sums is defined as your ''ratio range''. This is how far you can deviate your ratio both higher and lower from your benchmark ratio. It can be calculated by choosing boxes left and right of your chosen ratio on the chart above. Mo very seldom gives an extremely large ratio range. It is more common with very low or very high tilt. A +/- of around 0.5 above and 0.5 below benchmark ratio seems to be close to the average ratio range.<br />
<br />
You need to determine your personal '''<u>''Ratio Range''</u>''' to use in conjunction with your '''<u>''Total Sums Range''</u>''' to accurately calculate layouts for your personal specs or sweet spot.<br />
<br />
*Mo frequently uses the lower ratio range for easier THS wet / dry patterns for more control and mid-lane reaction <br />
<br />
*Mo frequently uses the higher ratio range (a defined break shape) for flatter or more demanding patterns to create a stronger reaction to friction.<br />
<br />
Please note: On ratios less than 1:1, Mo sometimes expresses ratios with the val angle reduced to :1<br />
example: 1:1.25 would be expressed as .8:1 (.8:1=1:1.25, etc.)<br />
# '''Adjust the angles (ratio) for the design of the ball.'''<br />
##Mo will usually raise the ratios on balls which tend to roll early.<br />
##Mo will usually lower the ratios on balls which tend to be skid/flip.<br />
# '''Adjust the angles for the pattern the bowler wants to use the ball on.'''<br />

<br />
High tilt players use Pin to PAP distances of 4 1/2" to 5 3/4" (with Asymmetrical balls)<br />
*4 ½” Pin to PAP distance will make the ball come off the spot hard (more angular)<br />
*5 ¾” Pin to PAP distance will make the ball roll forward sooner<br><br><br />
<br />

<br />
Retaining Axis Rotation & Axis Tilt (increase skid, reduce flare):<br><br />
*To retain Axis Rotation and Axis Tilt in SYMMETRICAL equipment, we would tend towards longer pin-pap (> 4") distances, while ASYMMETRICAL equipment we use shorter pin-pap distances (< 3").<br />
<br />
Burning Off Axis Rotation & Axis Tilt (decrease skid, increase flare):<br><br />
*To burn off Axis Rotation and Axis Tilt quicker in SYMMETRICAL equipment, we would tend toward Max flare pin positions (3" - 4"), while longer pin distances (4"+) in ASYMMETRICAL equipment. <br />

.<br />
<br />
==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Understanding Sums of the <u>Benchmark Range</u> ''''' (neccessary for calculations)''=== <br />
The Benchmark Range is necessary for adjusting other layouts off from the benchmark layout so the bowler will not have to change their specs when playing various conditions (Long & Strong layout/Control layout/Mid-lane layout/Totally Strong layout/ etc). <br />
<br />
'''''Total sums (drilling angle + VAL angle) determines the length of ball motion until the roll phase.''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />
<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
====Example====<br />
Sweet spot of <u>100º sums</u> using '''(± 20º)''' for this example.<br />
<br />
For dry or short oil patterns to increase length, use <u>120º sums</u>. <br />
*Use a high ratio for ''<u>long and strong layouts</u>''... ''(longer and quicker reaction to the dry...more of a skid /snap ball motion)''.<br />
*Use a low ratio for ''<u>control layouts</u>''...''(slower/smoother reaction to the dry)''<br />
<br />
For oily or longer patterns to decrease length, use <u>80º sums</u>. ''(utilizing ratios to achieve the desired break shape)<br />
*Use a high ratio for ''<u>Totally Strong Layouts</u>''... ''(defined/sharp motion...quicker reaction to the dry)''<br />
*Use a low ratio for ''<u>mid-lane layouts</u>''...''(earlier/slower reaction to the dry...smoother & more continuous ball motion.)''<br />
<br />
.<br />
<br />
==Find Your Benchmark Ratio ''(by primarily analyzing tilt and rotation)''==<br />
'''''This is necessary to accurately calculate the drilling angle and the val angle individually.'''''<br />
<br />
For examples on how to do the math, see ''[[Dual_Angle_Ratio_Guide#Simple Math Examples|simple math examples]]''.<br />
<br />
<br />
==='''<u>Step #4</u>-Find The Initial Ratio From Axis Tilt'''===<br />
The middle column (''initial ratio benchmark range'') gives approximate ratios for bowlers with ''speed/revs = matched + normal rotation.''<br />
<br />
Please note: when creating the chart we used 50º to 55º as normal axis rotation. (45º is slightly low and 60º is slightly high)<br />
<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º (especially when accompanied by high rotation) use this [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]].<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º accompanied by low rotation use the chart below:<br />
*For low ''[[axis_tilt|axis tilt]]'' with very low revs use the chart below (even with high rotation):<br />
''Chart created by Athery''<br />
[[File:Ratiochart.png]]<br />
<br />
'''Special notes for axis tilt below 7º:'''<br />
With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />

<br />
==='''<u>Step #6</u> - Find The Ratio '''Range''' '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />

The maximum ratio and minimum ratio (drill angle and val angle) which should be utilized with your personal sweet sums is defined as your ''ratio range''. This is how far you can deviate your ratio both higher and lower from your benchmark ratio. It can be calculated by choosing boxes left and right of your chosen ratio on the chart above.

==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Understanding Sums of the <u>Benchmark Range</u> ''''' (neccessary for calculations)''=== <br />
The Benchmark Range is necessary for adjusting other layouts off from the benchmark layout so the bowler will not have to change their specs when playing various conditions (Long & Strong layout/Control layout/Mid-lane layout/Totally Strong layout/ etc). <br />
<br />
'''''Total sums (drilling angle + VAL angle) determines the length of ball motion until the roll phase.''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />
<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
====Example====<br />
Sweet spot of <u>100º sums</u> using '''(± 20º)''' for this example.<br />
<br />
For dry or short oil patterns to increase length, use <u>120º sums</u>. <br />
*Use a high ratio for ''<u>long and strong layouts</u>''... ''(longer and quicker reaction to the dry...more of a skid /snap ball motion)''.<br />
*Use a low ratio for ''<u>control layouts</u>''...''(slower/smoother reaction to the dry)''<br />
<br />
For oily or longer patterns to decrease length, use <u>80º sums</u>. ''(utilizing ratios to achieve the desired break shape)<br />
*Use a high ratio for ''<u>Totally Strong Layouts</u>''... ''(defined/sharp motion...quicker reaction to the dry)''<br />
*Use a low ratio for ''<u>mid-lane layouts</u>''...''(earlier/slower reaction to the dry...smoother & more continuous ball motion.)''<br />

<br />
<br />
==='''<u>Step #4</u>-Find The Initial Ratio From Axis Tilt'''===<br />
The middle column (''initial ratio benchmark range'') gives approximate ratios for bowlers with ''speed/revs = matched + normal rotation.''<br />
<br />
Please note: when creating the chart we used 50º to 55º as normal axis rotation. (45º is slightly low and 60º is slightly high)<br />
<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º (especially when accompanied by high rotation) use this [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]].<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º accompanied by low rotation use the chart below:<br />
*For low ''[[axis_tilt|axis tilt]]'' with very low revs use the chart below (even with high rotation):<br />
''Chart created by Athery''<br />
[[File:Ratiochart.png]]<br />
<br />
'''Special notes for axis tilt below 7º:'''<br />
With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />
Here is a [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]] on how to adjust Athery's chart, especially when low tilt is accompanied by high rotation.<br />
<br />
==='''<u>Step #5</u> - Adjust the Initial Ratio '''''(from Step #4 If bowler has high or low rotation)''===<br />
'''Amount of adjustment necessary depends on the relationship between rotation and ball speed.'''<br />
*High rotation and/or high rotation accentuated with speed dominance = ''decreased ratios'' (use boxes further right on the chart)<br />
*Low rotation and/or low rotation accentuated with rev dominance = ''increased ratios'' (use boxes further left on the chart)<br />
<br />
==='''<u>Step #6</u> - Find The Ratio <u><big>Range</big></u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />
<br />
The maximum ratio and minimum ratio (drill angle and val angle) which should be utilized with your personal sweet sums is defined as your ''ratio range''. This is how far you can deviate your ratio both higher and lower from your benchmark ratio. It can be calculated by choosing boxes left and right of your chosen ratio on the chart above. Mo very seldom gives an extremely large ratio range. It is more common with very low or very high tilt. A +/- of around 0.5 above and 0.5 below benchmark ratio seems to be close to the average ratio range.<br />
<br />
You need to determine your personal ''ratio range'' to use in conjunction with your ''total sums'' to accurately calculate layouts for your personal specs or sweet spot.<br />
<br />
*Mo frequently uses the lower ratio range for easier THS wet / dry patterns for more control and mid-lane reaction <br />
<br />
*Mo frequently uses the higher ratio range (a defined break shape) for flatter or more demanding patterns to create a stronger reaction to friction.<br />
<br />
Please note: On ratios less than 1:1, Mo sometimes expresses ratios with the val angle reduced to :1<br />
example: 1:1.25 would be expressed as .8:1 (.8:1=1:1.25, etc.)<br />
# '''Adjust the angles (ratio) for the design of the ball.'''<br />
##Mo will usually raise the ratios on balls which tend to roll early.<br />
##Mo will usually lower the ratios on balls which tend to be skid/flip.<br />
# '''Adjust the angles for the pattern the bowler wants to use the ball on.'''<br />

==Pin to PAP distance will determine the amount of flare==<br />
<br />
==='''<u>Step #7</u>-Choose the Pin to PAP Distance''''' (for desired flare or desired amount of tilt & rotation retention)''===<br />
[[:image:Trackflarechart.JPG|Track Flare Chart]]<br />
<br />
'''Track Flare Discussion:'''<br />
<br />
High tilt players use Pin to PAP distances of 4 1/2" to 5 3/4" (with Asymmetrical balls)<br />
*4 ½” Pin to PAP distance will make the ball come off the spot hard (more angular)<br />
*5 ¾” Pin to PAP distance will make the ball roll forward sooner<br><br><br />
<br />
Asymmetrical Balls exhibit most flare at Pin to PAP distances of 2 3/4" to 6 1/4"<br><br />
Symmetrical Balls exhibit most flare with Pin to PAP distances of 3" to 4"<br><br><br />
<br />
Retaining Axis Rotation & Axis Tilt (increase skid, reduce flare):<br><br />
*To retain Axis Rotation and Axis Tilt in SYMMETRICAL equipment, we would tend towards longer pin-pap (> 4") distances, while ASYMMETRICAL equipment we use shorter pin-pap distances (< 3").<br />
<br />
Burning Off Axis Rotation & Axis Tilt (decrease skid, increase flare):<br><br />
*To burn off Axis Rotation and Axis Tilt quicker in SYMMETRICAL equipment, we would tend toward Max flare pin positions (3" - 4"), while longer pin distances (4"+) in ASYMMETRICAL equipment. <br />
.<br />
<br />
==Roll the ball==<br />
==='''<u>Step #8</u>-Use Balance Holes''' ''(if desired)''===<br />
<br />
With some extreme specs, the benchmark layout will include balance holes because the bowler will want balance holes in the majority of their equiptment.<br />
<br />
*Start with a smaller size hole (3/4") at least 2-1/2” deep<br />
*P1 hole = Reduces drilled dynamics<br />
*P2 hole = Maintains drilled dynamics<br />
*P3 hole = Increases drilled dynamics some<br />
*P4 hole = Increases drilled dynamics more<br />

==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Understanding Sums of the <u>Benchmark Range</u> ''''' (neccessary for calculations)''=== <br />
The Benchmark Range is necessary for adjusting other layouts off from the benchmark layout so the bowler will not have to change their specs when playing various conditions (Long & Strong layout/Control layout/Mid-lane layout/Totally Strong layout/ etc). <br />
<br />
'''''Total sums (drilling angle + VAL angle) determines the length of ball motion until the roll phase.''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />
<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
====Example====<br />

<br />
For dry or short oil patterns to increase length, use <u>120º sums</u>. <br />

==='''<u>Step #5</u> - Adjust the Initial Ratio '''''(from Step #4 If bowler has high or low rotation)''===<br />
'''Amount of adjustment necessary depends on the relationship between rotation and ball speed.'''<br />
*High rotation and/or high rotation accentuated with speed dominance = ''decreased ratios'' (use boxes further right on the chart)<br />

<br />
==='''<u>Step #6</u> - Find The Ratio <u><big>Range</big></u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />

With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />
Here is a [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]] on how to adjust Athery's chart, especially when low tilt is accompanied by high rotation.<br />

'''Amount of adjustment necessary depends on the relationship between rotation and ball speed.'''<br />
*High rotation and/or high rotation accentuated with speed dominance = ''decreased ratios'' (use boxes further right on the chart)<br />
*Low rotation and/or low rotation accentuated with rev dominance = ''increased ratios'' (use boxes further left on the chart)<br />
<br />
==='''<u>Step #6</u> - Find The Ratio <u><big>Range</big></u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />
The maximum ratio and minimum ratio (drill angle and val angle) which should be utilized with your personal sweet sums is defined as your ''ratio range''. This is how far you can deviate your ratio both higher and lower from your benchmark ratio. It can be calculated by choosing boxes left and right of your chosen ratio on the chart above. Mo very seldom gives an extremely large ratio range. It is more common with very low or very high tilt. A +/- of around 0.5 above and 0.5 below benchmark ratio seems to be close to the average ratio range.<br />
<br />
You need to determine your personal ''ratio range'' to use in conjunction with your ''total sums'' to accurately calculate layouts for your personal specs or sweet spot.<br />
<br />
*Mo frequently uses the lower ratio range for easier THS wet / dry patterns for more control and mid-lane reaction <br />
<br />
*Mo frequently uses the higher ratio range (a defined break shape) for flatter or more demanding patterns to create a stronger reaction to friction.<br />
<br />
Please note: On ratios less than 1:1, Mo sometimes expresses ratios with the val angle reduced to :1<br />
example: 1:1.25 would be expressed as .8:1 (.8:1=1:1.25, etc.)<br />

<br />
==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Understanding Sums of the <u>Benchmark Range</u> ''''' (neccessary for calculations)''=== <br />
The Benchmark Range is necessary for adjusting other layouts off from the benchmark layout so the bowler will not have to change their specs when playing various conditions (Long & Strong layout/Control layout/Mid-lane layout/Totally Strong layout/ etc). <br />
<br />
'''''Total sums (drilling angle + VAL angle) determines the length of ball motion until the roll phase.''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />
<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
====Example====<br />
Sweet spot of 100º using '''(± 20º)''' for this example.<br />
<br />
For dry or short oil patterns to increase length, use <u>120º sums</u>. <br />
*Use a high ratio for ''<u>long and strong layouts</u>''... ''(longer and quicker reaction to the dry...more of a skid /snap ball motion)''.<br />
*Use a low ratio for ''<u>control layouts</u>''...''(slower/smoother reaction to the dry)''<br />
<br />
For oily or longer patterns to decrease length, use <u>80º sums</u>. ''(utilizing ratios to achieve the desired break shape)<br />
*Use a high ratio for ''<u>Totally Strong Layouts</u>''... ''(defined/sharp motion...quicker reaction to the dry)''<br />
*Use a low ratio for ''<u>mid-lane layouts</u>''...''(earlier/slower reaction to the dry...smoother & more continuous ball motion.)''<br />
<br />
.<br />
<br />
==Find Your Benchmark Ratio ''(by primarily analyzing tilt and rotation)''==<br />
'''''This is necessary to accurately calculate the drilling angle and the val angle individually.'''''<br />
<br />
For examples on how to do the math, see ''[[Dual_Angle_Ratio_Guide#Simple Math Examples|simple math examples]]''.<br />
<br />
<br />
==='''<u>Step #4</u>-Find The Initial Ratio From Axis Tilt'''===<br />
The middle column (''initial ratio benchmark range'') gives approximate ratios for bowlers with ''speed/revs = matched + normal rotation.''<br />
<br />
Please note: when creating the chart we used 50º to 55º as normal axis rotation. (45º is slightly low and 60º is slightly high)<br />
<br />

<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />

* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />

If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Understanding Sums of the <u>Benchmark Range</u> ''''' (neccessary for calculations)''=== <br />
The Benchmark Range is necessary for calculating layouts which will not cause the bowler to have to change their specs by calculating their other layouts off from their benchmark layout to play various conditions (Long & Strong layout/Control layout/Mid-lane layout/Totally Strong layout/ etc). <br />
<br />
'''''Total sums (drilling angle + VAL angle) determines the length of ball motion until the roll phase.''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />

<br />
For dry or short oil patterns to increase length, use <u>120º sums</u>. <br />

<br />
For oily or longer patterns to decrease length, use <u>80º sums</u>. ''(utilizing ratios to achieve the desired break shape)<br />
*Use a high ratio for ''<u>Totally Strong Layouts</u>''... ''(defined/sharp motion...quicker reaction to the dry)''<br />

==='''<u>Step #4</u>-Find The Initial Ratio From Axis Tilt'''===<br />
The middle column (''initial ratio benchmark range'') gives approximate ratios for bowlers with ''speed/revs = matched + normal rotation.''<br />
<br />
Please note: when creating the chart we used 50º to 55º as normal axis rotation. (45º is slightly low and 60º is slightly high)<br />

<br />
'''Special notes for axis tilt below 7º:'''<br />
With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />
Here is a [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]] on how to adjust Athery's chart, especially when low tilt is accompanied by high rotation.<br />
<br />
==='''<u>Step #5</u> - Adjust the Initial Ratio '''''(from Step #4 If bowler has high or low rotation)''===<br />
'''Amount of adjustment necessary depends on the relationship between rotation and ball speed.'''<br />
*High rotation and/or high rotation accentuated with speed dominance = ''decreased ratios'' (use boxes further right on the chart)<br />
*Low rotation and/or low rotation accentuated with rev dominance = ''increased ratios'' (use boxes further left on the chart)<br />
<br />
==='''<u>Step #6</u> - Find The Ratio <u><big>Range</big></u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />
The maximum ratio and minimum ratio (drill angle and val angle) which should be utilized with your personal sweet sums is defined as your ''ratio range''. This is how far you can deviate your ratio both higher and lower from your benchmark ratio. It can be calculated by choosing boxes left and right of your chosen ratio on the chart above. Mo very seldom gives an extremely large ratio range. It is more common with very low or very high tilt. A +/- of around 0.5 above and 0.5 below benchmark ratio seems to be close to the average ratio range.<br />
<br />
You need to determine your personal ''ratio range'' to use in conjunction with your ''total sums'' to accurately calculate layouts for your personal specs or sweet spot.<br />
<br />
*Mo frequently uses the lower ratio range for easier THS wet / dry patterns for more control and mid-lane reaction <br />
<br />
*Mo frequently uses the higher ratio range (a defined break shape) for flatter or more demanding patterns to create a stronger reaction to friction.<br />
<br />
Please note: On ratios less than 1:1, Mo sometimes expresses ratios with the val angle reduced to :1<br />
example: 1:1.25 would be expressed as .8:1 (.8:1=1:1.25, etc.)<br />

[[:image:Trackflarechart.JPG|Track Flare Chart]]<br />
<br />
'''Track Flare Discussion:'''<br />
<br />
High tilt players use Pin to PAP distances of 4 1/2" to 5 3/4" (with Asymmetrical balls)<br />
*4 ½” Pin to PAP distance will make the ball come off the spot hard (more angular)<br />
*5 ¾” Pin to PAP distance will make the ball roll forward sooner<br><br><br />
<br />
Asymmetrical Balls exhibit most flare at Pin to PAP distances of 2 3/4" to 6 1/4"<br><br />
Symmetrical Balls exhibit most flare with Pin to PAP distances of 3" to 4"<br><br><br />
<br />
Retaining Axis Rotation & Axis Tilt (increase skid, reduce flare):<br><br />
*To retain Axis Rotation and Axis Tilt in SYMMETRICAL equipment, we would tend towards longer pin-pap (> 4") distances, while ASYMMETRICAL equipment we use shorter pin-pap distances (< 3").<br />
<br />
Burning Off Axis Rotation & Axis Tilt (decrease skid, increase flare):<br><br />
*To burn off Axis Rotation and Axis Tilt quicker in SYMMETRICAL equipment, we would tend toward Max flare pin positions (3" - 4"), while longer pin distances (4"+) in ASYMMETRICAL equipment. <br />
.<br />
<br />
==Roll the ball==<br />
==='''<u>Step #8</u>-Use Balance Holes''' ''(if desired)''===<br />
<br />
With some extreme specs, the benchmark layout will include balance holes because the bowler will want balance holes in the majority of their equiptment.<br />
<br />
*Start with a smaller size hole (3/4") at least 2-1/2” deep<br />

<br />
==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Understanding Sums of the <u>Benchmark Range</u> ''''' (neccessary for calculations)''=== <br />
The Benchmark Range is necessary for calculating layouts which will not cause the bowler to have to change their specs by adjusting off from their benchmark layout to play various conditions (Long & Strong layout/Control layout/Mid-lane layout/Totally Strong layout/ etc). <br />

# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />

A +/- of around 0.5 above and 0.5 below benchmark ratio seems to be close to the average ratio range.<br />
<br />
You need to determine your personal ''ratio range'' to use in conjunction with your ''total sums'' to accurately calculate layouts for your personal specs or sweet spot.<br />
<br />
*Mo frequently uses the lower ratio range for easier THS wet / dry patterns for more control and mid-lane reaction <br />
<br />
*Mo frequently uses the higher ratio range (a defined break shape) for flatter or more demanding patterns to create a stronger reaction to friction.<br />
<br />
Please note: On ratios less than 1:1, Mo sometimes expresses ratios with the val angle reduced to :1<br />
example: 1:1.25 would be expressed as .8:1 (.8:1=1:1.25, etc.)<br />

<br />
==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Understanding Sums of the <u>Benchmark Range</u> ''''' (neccessary for calculations)''=== <br />
The Benchmark Range is necessary for calculating layouts which will not cause the bowler to have to change their specs by adjusting off from their benchmark layout for other conditions (Long & Strong layout/Control layout/Mid-lane layout/Totally Strong layout/ etc). <br />
<br />
'''''Total sums (drilling angle + VAL angle) determines the length of ball motion until the roll phase.''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />
<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
====Example====<br />
Sweet spot of 100º using '''(± 20º)''' for this example.<br />
<br />
For dry or short oil patterns to increase length, use <u>120º sums</u>. <br />
*Use a high ratio for ''<u>long and strong layouts</u>''... ''(longer and quicker reaction to the dry...more of a skid /snap ball motion)''.<br />
*Use a low ratio for ''<u>control layouts</u>''...''(slower/smoother reaction to the dry)''<br />
<br />
For oily or longer patterns to decrease length, use <u>80º sums</u>. ''(utilizing ratios to achieve the desired break shape)<br />
*Use a high ratio for ''<u>Totally Strong Layouts</u>''... ''(defined/sharp motion...quicker reaction to the dry)''<br />
*Use a low ratio for ''<u>mid-lane layouts</u>''...''(earlier/slower reaction to the dry...smoother & more continuous ball motion.)''<br />
<br />
.<br />
<br />
==Find Your Benchmark Ratio ''(primarily analyzing tilt and rotation)''==<br />
'''''This is necessary to accurately calculate the drilling angle and the val angle individually.'''''<br />
<br />
For examples on how to do the math, see ''[[Dual_Angle_Ratio_Guide#Simple Math Examples|simple math examples]]''.<br />
<br />
<br />
==='''<u>Step #4</u>-Find The Initial Ratio From Axis Tilt'''===<br />
The middle column (''initial ratio benchmark range'') gives approximate ratios for bowlers with ''speed/revs = matched + normal rotation.''<br />
<br />
Please note: when creating the chart we used 50º to 55º as normal axis rotation. (45º is slightly low and 60º is slightly high)<br />
<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º (especially when accompanied by high rotation) use this [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]].<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º accompanied by low rotation use the chart below:<br />
*For low ''[[axis_tilt|axis tilt]]'' with very low revs use the chart below (even with high rotation):<br />
''Chart created by Athery''<br />
[[File:Ratiochart.png]]<br />
<br />
'''Special notes for axis tilt below 7º:'''<br />
With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />
Here is a [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]] on how to adjust Athery's chart, especially when low tilt is accompanied by high rotation.<br />
<br />
==='''<u>Step #5</u> - Adjust the Initial Ratio '''''(from Step #4 If bowler has high or low rotation)''===<br />
'''Amount of adjustment necessary depends on the relationship between rotation and ball speed.'''<br />
*High rotation and/or high rotation accentuated with speed dominance = ''decreased ratios'' (use boxes further right on the chart)<br />
*Low rotation and/or low rotation accentuated with rev dominance = ''increased ratios'' (use boxes further left on the chart)<br />
<br />
==='''<u>Step #6</u> - Find The Ratio <u><big>Range</big></u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />
The maximum ratio and minimum ratio (drill angle and val angle) which should be utilized with your personal sweet sums is defined as your ''ratio range''. This is how far you can deviate your ratio both higher and lower from your benchmark ratio. It can be calculated by choosing boxes left and right of your chosen ratio on the chart above. Mo very seldom gives an extremely large ratio range. It is more common with very low or very high tilt. A +/- of around 0.5 above and 0.5 below benchmark ratio seems to be close to the average ratio range.<br />

'''Special notes for axis tilt below 7º:'''<br />
With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />

<br />
==='''<u>Step #6</u> - Find The Ratio <u><big>Range</big></u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />
The maximum ratio and minimum ratio (drill angle and val angle) which should be utilized with your personal sweet sums is defined as your ''ratio range''. This is how far you can deviate your ratio both higher and lower from your benchmark ratio. It can be calculated by choosing boxes left and right of your chosen ratio on the chart above. Mo very seldom gives an extremely large ratio range. It is more common with very low or very high tilt. A +/- of around 0.5 above and 0.5 below benchmark ratio seems to be close to the average ratio range.<br />
<br />
You need to determine your personal ''ratio range'' to use in conjunction with your ''total sums'' to accurately calculate layouts for your personal specs or sweet spot.<br />
<br />
*Mo frequently uses the lower ratio range for easier THS wet / dry patterns for more control and mid-lane reaction <br />
<br />
*Mo frequently uses the higher ratio range (a defined break shape) for flatter or more demanding patterns to create a stronger reaction to friction.<br />
<br />

<br />
==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Determine your Total Sums <u>Benchmark Range</u> ''''' (neccessary for calculations)''=== <br />
Total Sums is neccessary for calculating layouts which will not cause the bowler to have to change their specs when deviating from their benchmark (Long & Strong/Control/Mid-lane/Totally Strong/ etc). <br />
<br />
'''''Total sums (drilling angle + VAL angle) determines the length of ball motion until the roll phase.''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />

<br />
==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Determine your Total Sums <u><big>Range</big></u> for your benchmark''''' (for symbiotic layouts)''===<br />
We are referring to layouts which should play off your benchmark layout without causing you to have to change your specs in order for them to be effective (Long & Strong/Control/Mid-lane/Totally Strong/ etc.)<br />
# The ''drill angle'' helps determine the length of the ''skid phase'' of ball motion.<br />
# The ''val angle'' helps determine the length of the ''hook phase'' of ball motion.<br />
# The ''drill angle + val angle'' = the total length of ball motion before the ball reaches the ''roll phase''. <br />
<br />
'''''Total sums determines the length of ball motion until the roll phase''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />
<br />
====Example====<br />
Sweet spot of 100º using '''(± 20º)''' for this example.<br />
<br />
For dry or short oil patterns to increase' length, use <u>120º sums</u>. <br />
*Use a high ratio for ''long and strong layouts''.<br />
*Use a low ratio for ''control layouts''.<br />
<br />
For oily or longer patterns to decrease length, use <u>80º sums</u>. ''(utilizing ratios to achieve the desired break shape)<br />
*Use a high ratio for ''defined/sharp motion''.<br />
*Use a low ratio for ''mid-lane roll''.<br />
'''Ratio Discussion:'''<br />
'''''Ratios determine the balls break shape.'''''<br />
<br />
# The ''drill angle'' helps determine the length of the ''skid phase'' of ball motion.<br />
# The ''val angle'' helps determine the length of the ''hook phase'' of ball motion.<br />
# The ''drill angle + val angle'' = the total length of ball motion before the ball reaches the ''roll phase''. <br />
## A higher ratio of the drill angle to the val angle = ''longer and quicker'' reaction to the dry. ''(more of a skid /snap ball motion) <br />
## A lower ratio of the drill angle to the val angle = ''earlier and slower'' reaction to the dry ''(smoother & more continuous ball motion.)''<br />
<br />
<br />
.<br />
<br />
<br />
.<br />
<br />
==Find Your Benchmark Ratio ''(primarily analyzing tilt and rotation)''==<br />
'''''This is necessary to accurately calculate the drilling angle and the val angle individually.'''''<br />
<br />
For examples on how to do the math, see ''[[Dual_Angle_Ratio_Guide#Simple Math Examples|simple math examples]]''.<br />
<br />
<br />
==='''<u>Step #4</u>-Find The Initial Ratio From Axis Tilt'''===<br />
The middle column (''initial ratio benchmark range'') gives approximate ratios for bowlers with ''speed/revs = matched + normal rotation.''<br />
<br />
Please note: when creating the chart we used 50º to 55º as normal axis rotation. (45º is slightly low and 60º is slightly high)<br />
<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º (especially when accompanied by high rotation) use this [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]].<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º accompanied by low rotation use the chart below:<br />
*For low ''[[axis_tilt|axis tilt]]'' with very low revs use the chart below (even with high rotation):<br />
''Chart created by Athery''<br />
[[File:Ratiochart.png]]<br />
<br />
'''Special notes for axis tilt below 7º:'''<br />
With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />
Here is a [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]] on how to adjust Athery's chart, especially when low tilt is accompanied by high rotation.<br />
<br />
==='''<u>Step #5</u> - Adjust the Initial Ratio '''''(from Step #4 If bowler has high or low rotation)''===<br />
'''Amount of adjustment necessary depends on the relationship between rotation and ball speed.'''<br />
*High rotation and/or high rotation accentuated with speed dominance = ''decreased ratios'' (use boxes further right on the chart)<br />
*Low rotation and/or low rotation accentuated with rev dominance = ''increased ratios'' (use boxes further left on the chart)<br />
<br />
==='''<u>Step #6</u> - Find The Ratio <u><big>Range</big></u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />
The maximum ratio and minimum ratio (drill angle and val angle) which should be utilized with your personal sweet sums is defined as your ''ratio range''. This is how far you can deviate your ratio both higher and lower from your benchmark ratio. It can be calculated by choosing boxes left and right of your chosen ratio on the chart above. Mo very seldom gives an extremely large ratio range. It is more common with very low or very high tilt. A +/- of around 0.5 above and 0.5 below benchmark ratio seems to be close to the average ratio range.<br />
<br />
You need to determine your personal ''ratio range'' to use in conjunction with your ''total sums'' to accurately calculate layouts for your personal specs or sweet spot.<br />
<br />
*Mo frequently uses the lower ratio range for easier THS wet / dry patterns for more control and mid-lane reaction <br />
<br />
*Mo frequently uses the higher ratio range (a defined break shape) for flatter or more demanding patterns to create a stronger reaction to friction.<br />
<br />
Please note: On ratios less than 1:1, Mo sometimes expresses ratios with the val angle reduced to :1<br />
example: 1:1.25 would be expressed as .8:1 (.8:1=1:1.25, etc.)<br />
<br />
==Pin to PAP distance will determine the amount of flare==<br />
<br />
==='''<u>Step #7</u>-Choose the Pin to PAP Distance''''' (for flare or retention of tilt & rotation as desired)''===<br />
[[:image:Trackflarechart.JPG|Track Flare Chart]]<br />
<br />
'''Track Flare Discussion:'''<br />
<br />
High tilt players use Pin to PAP distances of 4 1/2" to 5 3/4" (with Asymmetrical balls)<br />
*4 ½” Pin to PAP distance will make the ball come off the spot hard (more angular)<br />
*5 ¾” Pin to PAP distance will make the ball roll forward sooner<br><br><br />
<br />
Asymmetrical Balls exhibit most flare at Pin to PAP distances of 2 3/4" to 6 1/4"<br><br />
Symmetrical Balls exhibit most flare with Pin to PAP distances of 3" to 4"<br><br><br />
<br />
Retaining Axis Rotation & Axis Tilt (increase skid, reduce flare):<br><br />
*To retain Axis Rotation and Axis Tilt in SYMMETRICAL equipment, we would tend towards longer pin-pap (> 4") distances, while ASYMMETRICAL equipment we use shorter pin-pap distances (< 3").<br />
<br />
Burning Off Axis Rotation & Axis Tilt (decrease skid, increase flare):<br><br />
*To burn off Axis Rotation and Axis Tilt quicker in SYMMETRICAL equipment, we would tend toward Max flare pin positions (3" - 4"), while longer pin distances (4"+) in ASYMMETRICAL equipment. <br />
.<br />
<br />
==Roll the ball==<br />
==='''<u>Step #8</u>-Use Balance Holes''' ''(if desired)''===<br />
<br />
With some extreme specs, the benchmark layout will include balance holes because the bowler will want balance holes in the majority of their equiptment.<br />

==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />

Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />

<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />

# The ''val angle'' helps determine the length of the ''hook phase'' of ball motion.<br />

<br />
'''''Total sums determines the length of ball motion until the roll phase''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />

<br />
====Example====<br />
Sweet spot of 100º using '''(± 20º)''' for this example.<br />
<br />
For dry or short oil patterns to increase' length, use <u>120º sums</u>. <br />

Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />

<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />

==='''<u>Step #3</u>-Determine your Benchmark Total Sums <u><big>Range</big></u>''''' (for symbiotic layouts matching your specs)''===<br />
We are referring to layouts which should play off your benchmark layout without causing you to have to change your specs in order for them to be effective (Long & Strong/Control/Mid-lane/Totally Strong/ etc.)<br />
# The ''drill angle'' helps determine the length of the ''skid phase'' of ball motion.<br />
# The ''val angle'' helps determine the length of the ''hook phase'' of ball motion.<br />
# The ''drill angle + val angle'' = the total length of ball motion before the ball reaches the ''roll phase''. <br />
<br />
'''''Total sums determines the length of ball motion until the roll phase''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />
<br />
====Example====<br />
Sweet spot of 100º using '''(± 20º)''' for this example.<br />
<br />
For dry or short oil patterns to increase' length, use <u>120º sums</u>. <br />
*Use a high ratio for ''long and strong layouts''.<br />
*Use a low ratio for ''control layouts''.<br />
<br />
For oily or longer patterns to decrease length, use <u>80º sums</u>. ''(utilizing ratios to achieve the desired break shape)<br />
*Use a high ratio for ''defined/sharp motion''.<br />
*Use a low ratio for ''mid-lane roll''.<br />

# The ''drill angle + val angle'' = the total length of ball motion before the ball reaches the ''roll phase''. <br />
## A higher ratio of the drill angle to the val angle = ''longer and quicker'' reaction to the dry. ''(more of a skid /snap ball motion) <br />
## A lower ratio of the drill angle to the val angle = ''earlier and slower'' reaction to the dry ''(smoother & more continuous ball motion.)''<br />

<br />
==='''<u>Step #4</u>-Find The Initial Ratio From Axis Tilt'''===<br />
The middle column (''initial ratio benchmark range'') gives approximate ratios for bowlers with ''speed/revs = matched + normal rotation.''<br />
<br />
Please note: when creating the chart we used 50º to 55º as normal axis rotation. (45º is slightly low and 60º is slightly high)<br />
<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º (especially when accompanied by high rotation) use this [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]].<br />

[[File:Ratiochart.png]]<br />
<br />
'''Special notes for axis tilt below 7º:'''<br />
With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />
Here is a [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]] on how to adjust Athery's chart, especially when low tilt is accompanied by high rotation.<br />
<br />
==='''<u>Step #5</u> - Adjust the Initial Ratio '''''(from Step #4 If bowler has high or low rotation)''===<br />
'''Amount of adjustment necessary depends on the relationship between rotation and ball speed.'''<br />
*High rotation and/or high rotation accentuated with speed dominance = ''decreased ratios'' (use boxes further right on the chart)<br />
*Low rotation and/or low rotation accentuated with rev dominance = ''increased ratios'' (use boxes further left on the chart)<br />
<br />
==='''<u>Step #6</u> - Find The Ratio <u><big>Range</big></u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />
The maximum ratio and minimum ratio (drill angle and val angle) which should be utilized with your personal sweet sums is defined as your ''ratio range''. This is how far you can deviate your ratio both higher and lower from your benchmark ratio. It can be calculated by choosing boxes left and right of your chosen ratio on the chart above. Mo very seldom gives an extremely large ratio range. It is more common with very low or very high tilt. A +/- of around 0.5 above and 0.5 below benchmark ratio seems to be close to the average ratio range.<br />
<br />
You need to determine your personal ''ratio range'' to use in conjunction with your ''total sums'' to accurately calculate layouts for your personal specs or sweet spot.<br />
<br />
*Mo frequently uses the lower ratio range for easier THS wet / dry patterns for more control and mid-lane reaction <br />
<br />
*Mo frequently uses the higher ratio range (a defined break shape) for flatter or more demanding patterns to create a stronger reaction to friction.<br />
<br />
Please note: On ratios less than 1:1, Mo sometimes expresses ratios with the val angle reduced to :1<br />
example: 1:1.25 would be expressed as .8:1 (.8:1=1:1.25, etc.)<br />

==Pin to PAP distance will determine the amount of flare==<br />
<br />
==='''<u>Step #7</u>-Choose the Pin to PAP Distance''''' (for flare or retention of tilt & rotation as desired)''===<br />
[[:image:Trackflarechart.JPG|Track Flare Chart]]<br />
<br />
'''Track Flare Discussion:'''<br />
<br />
High tilt players use Pin to PAP distances of 4 1/2" to 5 3/4" (with Asymmetrical balls)<br />
*4 ½” Pin to PAP distance will make the ball come off the spot hard (more angular)<br />
*5 ¾” Pin to PAP distance will make the ball roll forward sooner<br><br><br />
<br />
Asymmetrical Balls exhibit most flare at Pin to PAP distances of 2 3/4" to 6 1/4"<br><br />
Symmetrical Balls exhibit most flare with Pin to PAP distances of 3" to 4"<br><br><br />
<br />
Retaining Axis Rotation & Axis Tilt (increase skid, reduce flare):<br><br />
*To retain Axis Rotation and Axis Tilt in SYMMETRICAL equipment, we would tend towards longer pin-pap (> 4") distances, while ASYMMETRICAL equipment we use shorter pin-pap distances (< 3").<br />
<br />
Burning Off Axis Rotation & Axis Tilt (decrease skid, increase flare):<br><br />
*To burn off Axis Rotation and Axis Tilt quicker in SYMMETRICAL equipment, we would tend toward Max flare pin positions (3" - 4"), while longer pin distances (4"+) in ASYMMETRICAL equipment. <br />
.<br />
<br />
==Roll the ball==<br />
==='''<u>Step #8</u>-Use Balance Holes''' ''(if desired)''===<br />
<br />
With some extreme specs, the benchmark layout will include balance holes because the bowler will want balance holes in the majority of their equiptment.<br />
<br />
*Start with a smaller size hole (3/4") at least 2-1/2” deep<br />
*P1 hole = Reduces drilled dynamics<br />
*P2 hole = Maintains drilled dynamics<br />
*P3 hole = Increases drilled dynamics some<br />
*P4 hole = Increases drilled dynamics more<br />

<br />
==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Determine your Total Sums <u><big>Range</big></u>''''' (for symbiotic layouts matching your specs)''===<br />
We are referring to layouts which should play off your benchmark layout without causing you to have to change your specs in order for them to be effective (Long & Strong/Control/Mid-lane/Totally Strong/ etc.)<br />
# The ''drill angle'' helps determine the length of the ''skid phase'' of ball motion.<br />
# The ''val angle'' helps determine the length of the ''hook phase'' of ball motion.<br />
# The ''drill angle + val angle'' = the total length of ball motion before the ball reaches the ''roll phase''. <br />
<br />
'''''Total sums determines the length of ball motion until the roll phase''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />
<br />
====Example====<br />
Sweet spot of 100º using '''(± 20º)''' for this example.<br />
<br />
For dry or short oil patterns to increase' length, use <u>120º sums</u>. <br />
*Use a high ratio for ''long and strong layouts''.<br />
*Use a low ratio for ''control layouts''.<br />
<br />
For oily or longer patterns to decrease length, use <u>80º sums</u>. ''(utilizing ratios to achieve the desired break shape)<br />
*Use a high ratio for ''defined/sharp motion''.<br />
*Use a low ratio for ''mid-lane roll''.<br />
'''Ratio Discussion:'''<br />
'''''Ratios determine the balls break shape.'''''<br />

Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />

<br />
==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Determine your Total Sums <u><big>Range</big></u>''''' (for symbiotic layouts matching your specs)''===<br />
We are referring to layouts which should play off your benchmark layout without causing you to have to change your specs in order for them to be effective (Long & Strong/Control/Mid-lane/Totally Strong/ etc.)<br />
<br />
'''''Total sums determines the length of ball motion until the roll phase''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
# Degree of drill angle + degree of val angle = Total Sums.<br />
## Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />
<br />
====Example====<br />
Sweet spot of 100º using '''(± 20º)''' for this example.<br />
<br />
For dry or short oil patterns to increase' length, use <u>120º sums</u>. <br />
*Use a high ratio for ''long and strong layouts''.<br />
*Use a low ratio for ''control layouts''.<br />
<br />
For oily or longer patterns to decrease length, use <u>80º sums</u>. ''(utilizing ratios to achieve the desired break shape)<br />
*Use a high ratio for ''defined/sharp motion''.<br />
*Use a low ratio for ''mid-lane roll''.<br />
<br />
.<br />
<br />
==Find Your Benchmark Ratio ''(primarily analyzing tilt and rotation)''==<br />
'''''This is necessary to accurately calculate the drilling angle and the val angle individually.'''''<br />
<br />
For examples on how to do the math, see ''[[Dual_Angle_Ratio_Guide#Simple Math Examples|simple math examples]]''.<br />
<br />
<br />
==='''<u>Step #4</u>-Find The Initial Ratio From Axis Tilt'''===<br />
The middle column (''initial ratio benchmark range'') gives approximate ratios for bowlers with ''speed/revs = matched + normal rotation.''<br />
<br />
Please note: when creating the chart we used 50º to 55º as normal axis rotation. (45º is slightly low and 60º is slightly high)<br />
<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º (especially when accompanied by high rotation) use this [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]].<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º accompanied by low rotation use the chart below:<br />
*For low ''[[axis_tilt|axis tilt]]'' with very low revs use the chart below (even with high rotation):<br />
''Chart created by Athery''<br />
[[File:Ratiochart.png]]<br />
<br />
'''Special notes for axis tilt below 7º:'''<br />
With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />
Here is a [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]] on how to adjust Athery's chart, especially when low tilt is accompanied by high rotation.<br />
<br />
==='''<u>Step #5</u> - Adjust the Initial Ratio '''''(from Step #4 If bowler has high or low rotation)''===<br />
'''Amount of adjustment necessary depends on the relationship between rotation and ball speed.'''<br />
*High rotation and/or high rotation accentuated with speed dominance = ''decreased ratios'' (use boxes further right on the chart)<br />
*Low rotation and/or low rotation accentuated with rev dominance = ''increased ratios'' (use boxes further left on the chart)<br />
<br />
==='''<u>Step #6</u> - Find The Ratio <u><big>Range</big></u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />

For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Determine your Total Sums <u><big>Range</big></u>''''' (for symbiotic layouts matching your specs)''===<br />
We are referring to layouts which should play off your benchmark layout without causing you to have to change your specs in order for them to be effective (Long & Strong/Control/Mid-lane/Totally Strong/ etc.)<br />
<br />
'''''Total sums determines the length of ball motion until the roll phase''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
# Degree of drill angle + degree of val angle = Total Sums.<br />
## Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />

<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />

*Use a high ratio for ''defined/sharp motion''.<br />
*Use a low ratio for ''mid-lane roll''.<br />

<br />
==='''<u>Step #4</u>-Find The Initial Ratio From Axis Tilt'''===<br />
The middle column (''initial ratio benchmark range'') gives approximate ratios for bowlers with ''speed/revs = matched + normal rotation.''<br />
<br />
Please note: when creating the chart we used 50º to 55º as normal axis rotation. (45º is slightly low and 60º is slightly high)<br />
<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º (especially when accompanied by high rotation) use this [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]].<br />

[[File:Ratiochart.png]]<br />
<br />
'''Special notes for axis tilt below 7º:'''<br />
With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />
Here is a [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]] on how to adjust Athery's chart, especially when low tilt is accompanied by high rotation.<br />
<br />
==='''<u>Step #5</u> - Adjust the Initial Ratio '''''(from Step #4 If bowler has high or low rotation)''===<br />
'''Amount of adjustment necessary depends on the relationship between rotation and ball speed.'''<br />
*High rotation and/or high rotation accentuated with speed dominance = ''decreased ratios'' (use boxes further right on the chart)<br />
*Low rotation and/or low rotation accentuated with rev dominance = ''increased ratios'' (use boxes further left on the chart)<br />
<br />
==='''<u>Step #6</u> - Find The Ratio <u><big>Range</big></u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />
The maximum ratio and minimum ratio (drill angle and val angle) which should be utilized with your personal sweet sums is defined as your ''ratio range''. This is how far you can deviate your ratio both higher and lower from your benchmark ratio. It can be calculated by choosing boxes left and right of your chosen ratio on the chart above. Mo very seldom gives an extremely large ratio range. It is more common with very low or very high tilt. A +/- of around 0.5 above and 0.5 below benchmark ratio seems to be close to the average ratio range.<br />
<br />
You need to determine your personal ''ratio range'' to use in conjunction with your ''total sums'' to accurately calculate layouts for your personal specs or sweet spot.<br />
<br />
*Mo frequently uses the lower ratio range for easier THS wet / dry patterns for more control and mid-lane reaction <br />
<br />
*Mo frequently uses the higher ratio range (a defined break shape) for flatter or more demanding patterns to create a stronger reaction to friction.<br />
<br />
Please note: On ratios less than 1:1, Mo sometimes expresses ratios with the val angle reduced to :1<br />
example: 1:1.25 would be expressed as .8:1 (.8:1=1:1.25, etc.)<br />
<br />
==Ratio Discussion==<br />
'''''Ratios determine the balls break shape.'''''<br />
<br />
# The ''drill angle'' helps determine the length of the ''skid phase'' of ball motion.<br />
# The ''val angle'' helps determine the length of the ''hook phase'' of ball motion.<br />
# The ''drill angle + val angle'' = the total length of ball motion before the ball reaches the ''roll phase''. <br />
## A higher ratio of the drill angle to the val angle = ''longer and quicker'' reaction to the dry. ''(more of a skid /snap ball motion) <br />
## A lower ratio of the drill angle to the val angle = ''earlier and slower'' reaction to the dry ''(smoother & more continuous ball motion.)''<br />

==='''<u>Step #7</u>-Choose the Pin to PAP Distance''''' (for flare or retention of tilt & rotation as desired)''===<br />
[[:image:Trackflarechart.JPG|Track Flare Chart]]<br />
<br />
High tilt players use Pin to PAP distances of 4 1/2" to 5 3/4" (with Asymmetrical balls)<br />
*4 ½” Pin to PAP distance will make the ball come off the spot hard (more angular)<br />
*5 ¾” Pin to PAP distance will make the ball roll forward sooner<br><br><br />
<br />
Asymmetrical Balls exhibit most flare at Pin to PAP distances of 2 3/4" to 6 1/4"<br><br />
Symmetrical Balls exhibit most flare with Pin to PAP distances of 3" to 4"<br><br><br />
<br />
Retaining Axis Rotation & Axis Tilt (increase skid, reduce flare):<br><br />
*To retain Axis Rotation and Axis Tilt in SYMMETRICAL equipment, we would tend towards longer pin-pap (> 4") distances, while ASYMMETRICAL equipment we use shorter pin-pap distances (< 3").<br />
<br />
Burning Off Axis Rotation & Axis Tilt (decrease skid, increase flare):<br><br />
*To burn off Axis Rotation and Axis Tilt quicker in SYMMETRICAL equipment, we would tend toward Max flare pin positions (3" - 4"), while longer pin distances (4"+) in ASYMMETRICAL equipment. <br />
.<br />
<br />
==Roll the ball==<br />
==='''<u>Step #8</u>-Use Balance Holes''' ''(if desired)''===<br />
<br />
With some extreme specs, the benchmark layout will include balance holes because the bowler will want balance holes in the majority of their equiptment.<br />

*Start with a smaller size hole (3/4") at least 2-1/2” deep<br />
*P1 hole = Reduces drilled dynamics<br />
*P2 hole = Maintains drilled dynamics<br />

<br />
==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />

## Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
*± 30° for elite bowlers<br />

# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />

<br />
For dry or short oil patterns to increase' length, use <u>120º sums</u>. <br />
*Use a high ratio for ''long and strong layouts''.<br />
*Use a low ratio for ''control layouts''.<br />
<br />

<br />
You need to determine your personal ''ratio range'' to use in conjunction with your ''total sums'' to accurately calculate layouts for your personal specs or sweet spot.<br />
<br />
*Mo frequently uses the lower ratio range for easier THS wet / dry patterns for more control and mid-lane reaction <br />
<br />
*Mo frequently uses the higher ratio range (a defined break shape) for flatter or more demanding patterns to create a stronger reaction to friction.<br />
<br />
Please note: On ratios less than 1:1, Mo sometimes expresses ratios with the val angle reduced to :1<br />
example: 1:1.25 would be expressed as .8:1 (.8:1=1:1.25, etc.)<br />

.<br />
<br />
==Find Your Benchmark Total Sums ''(primarily using speed/rev relationship)''==<br />
==='''<u>Step #1</u>- Determine the Initial Sums of angles''' ''(drilling angle + VAL angle)''.===<br />
Start your calculations by finding the relationship between ball speed and rev rate. An example of a well matched bowler would be 17mph speed and 300rpm (off the hand). For each 1mph increase or decrease in speed, a corresponding increase or decrease of about 50rpm would stay matched.<br />
Bowlers who are speed/revs matched would start their calculations with 95* of sums.<br />
[[:Image:BallSpeedvsRevRate.JPG|Link Text]]<br />
<br />
'''Rules of thumb''':<br />
<br />
* For the first 50 revs of imbalance ''(in excess)'', add 10* to the Total Sums.<br />
<br />
* For the first 1 mph of speed imbalance ''(in excess)'', subtract 10* from the Total Sums.<br />
<br />
If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Determine your Total Sums <u><big>Range</big></u>''''' (for symbiotic layouts matching your specs)''===<br />
We are referring to layouts which should play off your benchmark layout without causing you to have to change your specs in order for them to be effective (Long & Strong/Control/Mid-lane/Totally Strong/ etc.)<br />
<br />
'''''Total sums determines the length of ball motion until the roll phase''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
# Degree of drill angle + degree of val angle = Total Sums.<br />
## Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />
<br />
====Example====<br />
Sweet spot of 100º using '''(± 20º)''' for this example.<br />
<br />
For dry or short oil patterns to increase' length, use <u>120º sums</u>. <br />
*Use a high ratio for ''long and strong layouts''.<br />
*Use a low ratio for ''control layouts''.<br />
<br />
For oily or longer patterns to decrease length, use <u>80º sums</u>. ''(utilizing ratios to achieve the desired break shape)<br />
*Use a high ratio for ''defined/sharp motion''.<br />
*Use a low ratio for ''mid-lane roll''.<br />
<br />
.<br />
<br />
==Find Your Benchmark Ratio ''(primarily analyzing tilt and rotation)''==<br />
'''''This is necessary to accurately calculate the drilling angle and the val angle individually.'''''<br />
<br />
For examples on how to do the math, see ''[[Dual_Angle_Ratio_Guide#Simple Math Examples|simple math examples]]''.<br />
<br />
<br />
==='''<u>Step #4</u>-Find The Initial Ratio From Axis Tilt'''===<br />
The middle column (''initial ratio benchmark range'') gives approximate ratios for bowlers with ''speed/revs = matched + normal rotation.''<br />
<br />
Please note: when creating the chart we used 50º to 55º as normal axis rotation. (45º is slightly low and 60º is slightly high)<br />
<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º (especially when accompanied by high rotation) use this [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]].<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º accompanied by low rotation use the chart below:<br />
*For low ''[[axis_tilt|axis tilt]]'' with very low revs use the chart below (even with high rotation):<br />
''Chart created by Athery''<br />
[[File:Ratiochart.png]]<br />
<br />
'''Special notes for axis tilt below 7º:'''<br />
With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />
Here is a [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]] on how to adjust Athery's chart, especially when low tilt is accompanied by high rotation.<br />
<br />
==='''<u>Step #5</u> - Adjust the Initial Ratio '''''(from Step #4 If bowler has high or low rotation)''===<br />
'''Amount of adjustment necessary depends on the relationship between rotation and ball speed.'''<br />
*High rotation and/or high rotation accentuated with speed dominance = ''decreased ratios'' (use boxes further right on the chart)<br />
*Low rotation and/or low rotation accentuated with rev dominance = ''increased ratios'' (use boxes further left on the chart)<br />
<br />
==='''<u>Step #6</u> - Find The Ratio <u><big>Range</big></u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />
The maximum ratio and minimum ratio (drill angle and val angle) which should be utilized with your personal sweet sums is defined as your ''ratio range''. This is how far you can deviate your ratio both higher and lower from your benchmark ratio. It can be calculated by choosing boxes left and right of your chosen ratio on the chart above. Mo very seldom gives an extremely large ratio range. It is more common with very low or very high tilt. A +/- of around 0.5 above and 0.5 below benchmark ratio seems to be close to the average ratio range.<br />
<br />
You need to determine your personal ''ratio range'' to use in conjunction with your ''total sums'' to accurately calculate layouts for your personal specs or sweet spot.<br />
<br />
*Mo frequently uses the lower ratio range for easier THS wet / dry patterns for more control and mid-lane reaction <br />
<br />
*Mo frequently uses the higher ratio range (a defined break shape) for flatter or more demanding patterns to create a stronger reaction to friction.<br />
<br />
Please note: On ratios less than 1:1, Mo sometimes expresses ratios with the val angle reduced to :1<br />
example: 1:1.25 would be expressed as .8:1 (.8:1=1:1.25, etc.)<br />

If the speed/revs imbalance is <u>extremely</u> high or low, you would add or subtract extra sums to compensate accordingly. The amount of sums you add or subtract is not linear ''(for the second 50 revs of imbalance, you will add or subtract less than 10*, etc.)<br />
''<br />
<br />
==='''<u>Step #2</u>-Adjust Initial Sums''' ''(off from step #2 for very high or very low tilt & rotation)''.===<br />
Mo will also lower the sum of angles for bowlers with very high tilt & rotation, or raise the sum for bowlers with very low tilt & rotation.<br />
<br />
For these tilt adjustments, we are using '''13* to 17*''' of tilt as the normal tilt range.<br />
<br />
For these rotation adjustments, we are using '''45* to 60*''' of rotation as the normal rotation range.<br />
<br />
'''Rules of thumb:'''<br />
<br />
* Lower totals by about 10° for high tilt<br />
* Raise totals by about 10° for low tilt<br />
* Lower totals by about 5° for high rotation<br />
* Raise totals by about 5° for low rotation<br><br><br />
<br />
If the tilt or rotation is <u>extremely</u> high or low, you could add or subtract extra sums to compensate accordingly.<br />
<br />
==='''<u>Step #3</u>-Determine your Total Sums <u><big>Range</big></u>''''' (for symbiotic layouts matching your specs)''===<br />
We are referring to layouts which should play off your benchmark layout without causing you to have to change your specs in order for them to be effective (Long & Strong/Control/Mid-lane/Totally Strong/ etc.)<br />
<br />
'''''Total sums determines the length of ball motion until the roll phase''''' ''(See: [[Three_Phases_of_Ball_Motion|Three Phases of Ball Motion]])''<br />
<br />
# Degree of drill angle + degree of val angle = Total Sums.<br />
## Note: The total sums of your sweet spot will include a '''(+ or - of degrees)''' which is the <u>benchmark range</u>.<br />
*± 30° for elite bowlers<br />
*± 20° for good bowlers<br />
*± 10° for average bowlers<br><br><br />
<br />
# ''Adding'' these degrees to your total sums will add length to the ball motion. ''(increasing total length of ball motion before reaching the roll phase)''<br />
# ''Subtracting'' these degrees from your total sums will decrease the length of ball motion.<br />
<br />
====Example====<br />
Sweet spot of 100º using '''(± 20º)''' for this example.<br />
<br />
For dry or short oil patterns to increase' length, use <u>120º sums</u>. <br />
*Use a high ratio for ''long and strong layouts''.<br />
*Use a low ratio for ''control layouts''.<br />
<br />
For oily or longer patterns to decrease length, use <u>80º sums</u>. ''(utilizing ratios to achieve the desired break shape)<br />
*Use a high ratio for ''defined/sharp motion''.<br />
*Use a low ratio for ''mid-lane roll''.<br />
<br />

==Find Your Benchmark Ratio ''(primarily analyzing tilt and rotation)''==<br />
'''''This is necessary to accurately calculate the drilling angle and the val angle individually.'''''<br />
<br />

<br />
<br />
==='''<u>Step #4</u>-Find The Initial Ratio From Axis Tilt'''===<br />
The middle column (''initial ratio benchmark range'') gives approximate ratios for bowlers with ''speed/revs = matched + normal rotation.''<br />
<br />
Please note: when creating the chart we used 50º to 55º as normal axis rotation. (45º is slightly low and 60º is slightly high)<br />
<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º (especially when accompanied by high rotation) use this [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]].<br />
*For ''[[axis_tilt|axis tilt]]'' below 7º accompanied by low rotation use the chart below:<br />
*For low ''[[axis_tilt|axis tilt]]'' with very low revs use the chart below (even with high rotation):<br />

<br />
'''Special notes for axis tilt below 7º:'''<br />
With low tilt, the rotation seems to effect the ratios a lot more than with medium tilts. A high rotation will decrease them a lot (what Mo calls ''PDW territory'') and a low rotation will significantly raise them. There is more of an extreme adjustment comparitively.<br />
The ratios increase as the tilt decreases until you reach below 7º to 10º; below that the ratios decrease. Part of the reason is because the maximum drilling angle is 90º and with low tilt, you need ratios which will take the ball down the lane. <br />
Here is a [[:File:Decrease_low_tilt_on_Athery%27s_chart.pdf|PDF chart]] on how to adjust Athery's chart, especially when low tilt is accompanied by high rotation.<br />
<br />
==='''<u>Step #5</u> - Adjust the Initial Ratio '''''(from Step #4 If bowler has high or low rotation)''===<br />
'''Amount of adjustment necessary depends on the relationship between rotation and ball speed.'''<br />
*High rotation and/or high rotation accentuated with speed dominance = ''decreased ratios'' (use boxes further right on the chart)<br />
*Low rotation and/or low rotation accentuated with rev dominance = ''increased ratios'' (use boxes further left on the chart)<br />
<br />
==='''<u>Step #6</u> - Find The Ratio <u><big>Range</big></u> '''''(for calculating Long & Strong/Control/Mid-lane/Strong oil/Etc. layouts)''===<br />
The maximum ratio and minimum ratio (drill angle and val angle) which should be utilized with your personal sweet sums is defined as your ''ratio range''. This is how far you can deviate your ratio both higher and lower from your benchmark ratio. It can be calculated by choosing boxes left and right of your chosen ratio on the chart above. Mo very seldom gives an extremely large ratio range. It is more common with very low or very high tilt. A +/- of around 0.5 above and 0.5 below benchmark ratio seems to be close to the average ratio range.<br />
<br />
You need to determine your personal ''ratio range'' to use in conjunction with your ''total sums'' to accurately calculate layouts for your personal specs or sweet spot.<br />
<br />
*Mo frequently uses the lower ratio range for easier THS wet / dry patterns for more control and mid-lane reaction <br />
<br />
*Mo frequently uses the higher ratio range (a defined break shape) for flatter or more demanding patterns to create a stronger reaction to friction.<br />
<br />
Please note: On ratios less than 1:1, Mo sometimes expresses ratios with the val angle reduced to :1<br />
example: 1:1.25 would be expressed as .8:1 (.8:1=1:1.25, etc.)<br />
<br />
==Ratio Discussion==<br />
'''''Ratios determine the balls break shape.'''''<br />
<br />
# The ''drill angle'' helps determine the length of the ''skid phase'' of ball motion.<br />
# The ''val angle'' helps determine the length of the ''hook phase'' of ball motion.<br />
# The ''drill angle + val angle'' = the total length of ball motion before the ball reaches the ''roll phase''. <br />
## A higher ratio of the drill angle to the val angle = ''longer and quicker'' reaction to the dry. ''(more of a skid /snap ball motion) <br />
## A lower ratio of the drill angle to the val angle = ''earlier and slower'' reaction to the dry ''(smoother & more continuous ball motion.)''<br />

==Pin to PAP distance will determine the amount of flare==<br />
<br />
==='''<u>Step #7</u>-Choose the Pin to PAP Distance''''' (for flare or retention of tilt & rotation as desired)''===<br />
<br />
High tilt players use Pin to PAP distances of 4 1/2" to 5 3/4" (with Asymmetrical balls)<br />
*4 ½” Pin to PAP distance will make the ball come off the spot hard (more angular)<br />
*5 ¾” Pin to PAP distance will make the ball roll forward sooner<br><br><br />
<br />
Asymmetrical Balls exhibit most flare at Pin to PAP distances of 2 3/4" to 6 1/4"<br><br />
Symmetrical Balls exhibit most flare with Pin to PAP distances of 3" to 4"<br><br><br />
<br />
Retaining Axis Rotation & Axis Tilt (increase skid, reduce flare):<br><br />
*To retain Axis Rotation and Axis Tilt in SYMMETRICAL equipment, we would tend towards longer pin-pap (> 4") distances, while ASYMMETRICAL equipment we use shorter pin-pap distances (< 3").<br />
<br />
Burning Off Axis Rotation & Axis Tilt (decrease skid, increase flare):<br><br />
*To burn off Axis Rotation and Axis Tilt quicker in SYMMETRICAL equipment, we would tend toward Max flare pin positions (3" - 4"), while longer pin distances (4"+) in ASYMMETRICAL equipment. <br />
.<br />
<br />
==Roll the ball==<br />
==='''<u>Step #8</u>-Use Balance Holes''''' if desired''===<br />
<br />
With some extreme specs, the benchmark layout will include balance holes because the bowler will want balance holes in the majority of their equiptment.<br />
<br />
*Start with a smaller size hole (3/4") at least 2-1/2” deep<br />
*P1 hole = Reduces drilled dynamics<br />
*P2 hole = Maintains drilled dynamics<br />
*P3 hole = Increases drilled dynamics some<br />
*P4 hole = Increases drilled dynamics more<br />
