Patrick Johnson said:Your point WAS that the stroke influences the speed of the cue ball - at least that's what you said above.

...and that is exactly what I will say and I can show YOU shot after shot that can prove it.
I fully admit that I am not into the physics of the game as much as you are, but in this case it seems to have blocked you from seeing a different way of doing things. I say that respectfully, but honestly I can't believe you are actually arguing this.
Most of your tests will apply only to YOUR stroke and YOUR abilities.
Just because YOU can't do something with the cue ball or if you can't prove it with YOUR shooting or stroking ability - doesn't mean that holds true for everybody. Larry Nevel can do some unbelievable things with a cue ball that I am incapable of doing. The stuff Larry Nevel can do will defy all of your physics laws as well - especially if you test the physics of his abilities with your stroke.
Making a blanket statement that the cue ball won't move that way because of your tests seems a bit closed minded to me. My tests with that shot have different results than yours - and Flex's results are similar to mine - they are different because we each have different stroke mechanics.
