Aiming is difficult. Repeating a perfectly center ball stroke is comparable to winning the lottery. It is target shooting. What is more likely to happen are players learn how to shoot of center ball because it is easier then repeating the perfect stroke each shot.
Shooting off center requires some mastery of basic physics concerning rotations. The follow is shooting high center, the draw is shooting low center and I can demonstrate shooting left center creates a left path from the collision point and shooting right center creates a path to the right from the collision.
I did the experiment shooting two balls in relatively close maybe 1 diamond apart and applying the various stroke follow through paths, left center, right center, and it worked. Applying that idea to the angles in between is something still in the works.
SUMMARY: Follow is induced by high center stroke, draw with a low center stroke, the cue ball path post collision with an object ball can be controlled by the direction of the cue stroke and cue ball contact, in my work I can demonstrate perpendicular motion from the stroke path line after contact with an object ball, the findings were made when shooting two balls center lined 1 diamond apart with a center line stroke and left/right stroke follow through. These findings can be reproduced easily they just need peer confirmation.
