CG punch on a bowling ball


Definition

Definition 1: The point marked on the cover of the ball, indicating where the most top weight is, to be used in the drilling process
Definition 2: The actual center of gravity close to the center of the ball
It has been claimed to affect ball reaction enough to be important to consider CG when laying out a ball

Does CG Matter?

It's been an ongoing debate on internet message boards such as BallReviews.com to determine whether CG matters or not. Both sides, "CG Matters" and "CGNOMADDAH" have each come up with an argument each stating CG's effect on ball reaction. Below is a recap of each side's point(s).

  • The CG helps mark the Mass Bias on a Symmetrical ball. Although the strength of the Mass Bias is very low in symmetrical ball, it is a Mass Bias, nonetheless, and helps more precisely layout a bowling ball.

    • 1 Ounce of static weight accounts for 1/256th of the entire weight of a 16 pound bowling ball.
    • Shifting CG does NOT modify the orientation of the core.
    • Shifting CG does NOT modify track flare OR move the bowtie.
    • The effect of CG on ball reaction is less than the effect of bowler error, or the inability to repeat shots.
    • Brunswick video lane plot shows "little or no difference" in ball reaction.
