I watched the whole video with what you said in mind. Not a single stroke he took in the whole video had a de-accelerating cue at the point of contact. It was accelerating at the time of contact in every single shot. Also his grip tightens on the followthrough, I am not sure it is so loose in the warmup strokes. What he does is somewhat similar to alot of Filipino players, a loose grip with contact on the thumb, forefinger, and maybe middle finger and on the followthrough the ring finger and pinky come up to in effect "catch" the cue in the finish part of the stroke. There is absolutely NOTHING wrong with that and many word champion calibre players do that exact same thing.
Anyhow, which stroke do you think he is de-accelerating at the time of cueball contact, please clarify and tell us how you figure this to be the case.
Sure, that's what I do for an occupation.
Let's start with Physics. Any time you are going to stop your cue stick on purpose, the cue stick has to start slowing down before it can stop. Here is the problem.....when does it start de-accelerating? Have we never gone to draw the ball and hit a stop shot, or vs verse?
It is extremely difficult to maintain acceleration & accuracy consistency with a tight grip and de-accelerating pool stick. Maybe we can get by with it on a single shot but the game is all about re-producing the same accelerating stroke shot after shot.
