So... what is your point?
I think you are mixing up a few things in there. Do you think that a predominant feel player does not know how follow works or that all tables are not level or that all balls are not equal?
Depends. Some feel players seem to blow off stuff like this, like it's not important, but it can be, in certain situations.
Buffalo's had a table that the two long rails banked completely differently because of how the A/C vent on the wall blew on one but not the other.
There is a table at another hall that I know that has a badly cut shelf & will not accept balls coming from the short rail as well as from the long rail.
Would you say that knowing these things puts at an advantage, or disadvantage? If you came to a completely unknown pool hall with standard Gold Crowns/Diamonds, it and it was raining outside, would you pick the table by the open window, if so, would you know how to compensate, roughly? Or would you need to shoot x number of banks first?
I said that we all have our own type of 'nature' & should proceed on that as opposed to how others TELL us to do so.
Excuse me, but nobody is TELLING you to do jack sh...Do whatever you please. No need to say that others are wrong or stupid for knowing how the balls react. There are times in this game when people who know the physics can actually play a little. Otherwise, every hustler with read up on Dr. Daves page as part of their hustle.
Some love drills & some 'hate' drills. Some 'love' contrivances & others do not.
Ah "contrivances"
I can teach you how to throw a baseball & I can get you to throw it into the ground right in front of you & I can explain the physics & the angle that will allow you to throw the ball as far as you are capable.
I hope I don't offend you Americans now, but I'd rather be flayed alive than learn baseball. The only game more boring than that would be cricket. And no, I don't want to learn that, either.
I can NOT tell you that a throw from the right field corner to third base is a level 7.5 of 10 levels for you. You will just have to throw that throw (& others) a number of times and garner a feel for just what your arm is capable.
I can tell you right now that I'm not much of a ball thrower. I can only throw knives and axes. I can kick a ball quite far though.
As to the off shoot of the thread, do you think that everyone's peace sign is of the exact same angle?
Well, I can't guarantee that. But I like the fact that this doesnt' rely on equipment, but rather uses your own body for the calculations. If your peace sign is off, you'll see it.
Also do you know exactly what the rolling speed of a ball is vs one that will have some top spin coming out of the collision? Just how hard can you hit a ball so it will ONLY be rolling out of a collision? do you know exactly how man feet per second that is?
No. I don't see how that measurement would be possible to make with the naked eye. Also the slickness of the cloth plays a big part. That still doesn't prevent me from using calcualtions based on half ball hits. I also know some 3 cushion systems that help me with that.
Anyway... To each their own.
All Best Wishes for You & Yours,
