See, drillings are determined by the distance from the PAP to the Pin and CG. Since you're right handed, your PAP is the spot on the right side of the ball that is equidistant from your ball track. It is the spot that you rotate the ball around when you throw it.
As the pin gets closer to that spot, it will want to roll earlier since the core will be in an increasingly stable position. As it gets further away, the ball will want to lope down the lane since the core is wobbling and not rolling.
That's a very basic way to describe the relationship between PAP and Pin distance.
