Whether it CAN work after enough practice I don’t think anyone is debating. The simple fact is that tons of things in sports require the highest level of exact consistency. The level of success a person has is generally directly proportional to increasing consistency (call it robot like if you wish). The level of consistency is generally inversely proportional to the amount of variables in the action performed. A few examples- golf putt. When you get to where you can repeat the exact stance and same stroke upon your intended line, the only thing you change for length of putt is length of backswing. The variables I control are reduced essentially to 1. I cannot control course variables. If I, for some reason, wanted to I could always line up center cup, instead of my aim path that is adjusted to the actual path the slope and hills will cause it to roll on. From center cup aim I could control the direction of my putt by how much I roll my wrists through the stroke. This controls the angle of the face of my putter thereby determining direction of ball. This is as exact of a comparison as can be made to the method you describe. The problem with it is it introduces so many variables they cannot be accounted in the golf analogy I’ve arguably introduced the possibility of 44 different angles (assuming I’m covering 22.5 degrees either direction from the ideal 90 degree clubface) that are incorrect. I’ve went from adjusting length of backswing only which is still required in the 2nd method, to adding having to be perfectly timed with how much I’ve rolled my wrist at moment of impact. Can it be done? Sure. Anybody practicing anything long enough with enough dedication will gain muscle memory to become proficient. Go to a golf course and you’ll see some crazy stuff. Occasionally you’ll see crazy stuff on a scratch golfer. It’s the exception for a reason, though, and it’s the same reason you won’t see crazy stuff on tour. I have a million things to learn and improve upon before I would claim to be a proficient pool player. I know without a doubt that eliminating variables is how I get there. It’s how I’ve shot under par while not being a good golfer and it’s how I’ve bowled 299 and 300 games. It’s not that it can’t work it’s that it’s as inefficient as driving through Iowa to go from FL to GA
