It would be word games if it wasn't the original question and the reason I made this thread in the first place. Many people believe that it's not only harder but flat out impossible to perform certain shots without a smooth/well-timed stroke. E.g. two balls on opposite spots, drawing with side into corner pocket such that the CB never touches the end rail. Very delicate shot, not possible on certain cloth/tables/rails, typically requires cheating the pocket so pocket size helps. Easier with a good stroke 100%, but many people, including some good players, insist on the smoothness of the stroke being the "magic ingredient" that somehow turns it from impossible to possible. Literally, not just increasing the percent of success.
The fact that the thread is 80% about the benefits of good timing in general (ignoring the premise of the thread) is very expected. And I appreciate the discussion either way. It's a closely related topic, although one that almost everyone agree with. Highly doubt anyone in this thread questions that good timing helps in consistency. But natarddrho's answer was definitely not word games, he simply answered the original question precisely.
I would agree with you without that one phrase, about needing the same impulse. I could jump to the moon with the same impulse as a lunar rocket. Most of us have seen crazy things in a pool hall or on a bar table. Not repeatable without perhaps the ability of Venom, but as a one time instance, not absolutely impossible. I have seen cue balls land on top of lights, small lights. I saw a beautiful break, except for the minor detail that the shooter jumped the ball over the rack of balls he was shooting at, over the table, over the near end of the next table, and into the balls sitting there ready to be broken in another minute.
I can make many impossible things possible if I add the caveat "with the same impulse". If you want to add that, many one in millions things become possible. There were two bullets found on a battlefield. One had struck the side of the other one, jammed inside of it, and they stayed together to be found. The odds were one in tens of millions or more. Not impossible but as I said earlier, the kind of thing impossible to duplicate on demand.
You are trying to win arguments that something isn't impossible when there is some possibility of something happening from the beginning of time to the end of time, damned near anything is possible. If somebody makes a large bet on you making a pool shot and gives you a year to do it, you fail and I would say the shot is impossible for you.
Speaking of which, being a poor boy I'll cap the bet at ten thousand dollars that I can make a pool shot that you can't make in the next month. We both have to post. Want in? I will demonstrate the shot in one try and give you an unlimited number of tries in that month. Nothing to it!
