straightline: "Can you provide the logic behind this?"

I can't do a video right now, but maybe we can do it with words. I'm not sure what level you are starting from, so here are some basics. Do you understand these?
  1. The standard, simple ghost ball idea is that if the cue ball touches the object ball on its point farthest from the pocket, the object ball will be driven perfectly straight towards the pocket. At the instant of contact, the centers of the cue ball and object ball are on a line to the pocket.
  2. If you include the friction between the balls, and the cue ball is moving across the object ball -- like for a cut shot -- the object ball will be pulled off that ideal line by the sideways friction from the cue ball. This is called "throw".
Do both of those make sense?
Why do you assume I don't know how to do what your are discussing?

I wanted you or PJ or Bill to post a video demonstrating your point of view on the subject. Include not just pocketing the ball, but playing shape on another ball using a variety of spins.

Talking imo isn't doing.
