Bowler Specs Affecting Dual Angle Sweet Spot
- Ball speed
- Rev rate
- Axis tilt
- Axis rotation
Finding Your Benchmark Total Sums
STEP #1... Find Speed/Rev Relationship
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. Bowlers who are speed/revs matched would start their calculations with 95* of sums. Link Text
STEP #2...Adjust Sum For Speed/Rev Imbalance
Rules of thumb:
- For the first 50 revs of imbalance (in excess), add 10* to the Total Sums.
- For the first 1 mph of speed imbalance (in excess), subtract 10* from the Total Sums.
STEP #3...Adjust Sum (of step #2) for very high or very low tilt & rotation.
Mo will also lower the sum of angles for those with very high tilt & rotation, or raise the sum for those with very low tilt & rotation.
Rules of thumb:
- Lower totals by about 10° for very high tilt
- Raise totals by about 10° for very low tilt
- Lower totals by about 5° for very high rotation
- Raise totals by about 5° for very low rotation
