I'm going to give you my thoughts on locating the PAP, Ball Reaction/Motion. It is lengthy so I apologize, but hopefully this will help moving forward.
PAP TESTING:
- Place a 1x1 inch piece of white tape on your PAP
- When the ball leaves your hand and lands on the lane, the tape should remain stable, almost motionless on the ball.
- If the tape is not stable, then chances are your PAP is not marked properly and you should go through the steps necessary to retrace your PAP location.
BALL REACTION/MOTION TESTING:
- There are 3 phases of ball motion...SKID, HOOK, ROLL
- SKID PHASE - this is the first phase of ball motion and the one that works together with your PAP marking. When the ball is in the skid phase, it is rotating on your PAP and the tape is almost motionless on the ball. As it encounters friction, the tape becomes unstable and begins to move around the ball, entering the HOOK Phase.
- HOOK PHASE - this is the phase of ball motion where the ball begins flaring and core and cover begin working together to produce the balls reaction on the lane. During this phase, the new ball surface is coming in contact with the lane as it moves down the lane. Once the ball surface has stopped flaring, the ball enters the ROLL Phase.
- ROLL PHASE - this is the final phase of ball motion where the ball is basically slowing down the most and no longer creating new surface to lane contact. This is an important part of ball motion because entering this phase too soon can adversely affect carry potential of your bowling balls.
These are the things I think about when I'm ever having issues with ball reaction. Hope this helps you out.
