There is a very slight increase in the time of contact for an accelerating stroke. That's down in the 1% region, which is much smaller than the difference due to harder/softer tips which can be in the 50% region of decreased/increased contact time. Contact time also decreases for a faster shot but not with a direct proportion. If I recall correctly, if you double shot speed, the contact time reduces by about 20%.... Is the time that the tip is in contact with the cue ball the same with a decelerating stroke and accelerating stroke? ...
So, a soft tip & a slower accelerating stroke will result in an increased tip contact time over a hard tip at a faster accelerating speed?
I was just talking to Marc O. Who double dipped SVB in Sioux Falls a week ago. He owned the pool hall in Sioux Falls and knows SVB very well. Anyway he was explaining some of the shots Shane does and how he hits through the ball smoothly where it seems as if the tip is in contact longer. It might not be. Shane plays with a hard tip. Marc said it isn't something you can probably teach. Wish I knew the answer.

Rob,
I am fairly sure I understand. I do the 'same' thing even though I am using a soft tip. It's a longer than needed stroke at a much slower controlled acceleration that borders on deceleration. I even do one soft shot that my bridge hand oscillates up & down in tandem with my practice strokes & the final hit. I have tried to get the 'same' results without doing that but can not.
Disclaimer: I did not mean to compare myself to SVB. I just at times shoot a similiar shot.

I would think it would take a lot of practice. Does you wrist stay firm through your stroke

Might be a dumb question but what does all this tip contact time have to do with playing better pool?
Mr. Ken,
Perhaps oscillating was not the most appropriate word. Perhaps 'flexing' up & down would have been a better description. But yes, timing the hit with a bridge that is 'flexing' up on a soft shot with inside english accomplishes, for me, a result that I have not been able to duplicate exactly without the flexing bridge.
It's not that complicated but it is certainly, for me, only a specialty shot. I guess the effect might be similiar to hitting the ball high with a super soft 'sawing stroke' which I never use. I'm a piston stroke guy.
Thanks for getting me to clarify that. 'Oscillating' does seem complex unless super low frequency is attached to it.
Best Regards,
You give me too much credit for being serious.
I was just funning with you!

sparkle84...Good point...and the answer is nothing! The dwell time is around 1/1000th of the second (in comparison, a reflex eye blink takes about 4/1000the of a second)...give or take a few ten thousandths of a second. All it means is that longer followthroughs have no bearing on the outcome of the shot (since the CB is gone as soon as your tip strikes it). Knowing that may result in learning how to play better.

I knew were you were not chopping me off at the knees, but I'm sure there were others scratching their heads about an 'oscillating bridge hand'.
Best Regards,
I liked your original question a lot, Ken, and I too was interested in what Bob's answer would be. It makes me wonder about the relationship between good stroke timing and tip contact time. We may find some interesting answers in researching the same questions in golf, since the issues are the same ---- striking a non-moving ball.
I've often wondered whether an extended follow-through, particularly with a slower stroke may actually result in multiple hits on the cb rather than one hit of longer duration.
