Bet it's humans. My world would be all the sub tweeenies miss nothing do pool flawless and _then_ go out and learn the ropes.Too much paid for, failed instruction, and not enough practice and competition.
Jumping up.....Not following through.
Unnecessary elevation of the butt of their cue on nearly all shots.
And gripping on the butt cap*This* is what I see.
There was a pretty good sized event at my PR this past weekend and I was kinda shocked to see how high up in the air so many players had their grip. I mean it wasn't just a wee bit of elevation, the slope was way up there.
I'd take that a step farther and say an obsession with spin in general. Speed alone is much less difficult to control than speed AND spin. It's also much less difficult to pocket balls with less spin. While it is really fun to see the cue ball zing off the cushion, it's way more fun to consistently make the ball your shooting at and get position by letting the rock roll where it wants to go.obsession with draw
its natural to elevate the butt.
This was the thing I was going to mention. Even fairly good (up to 550 level) players, do this on nearly every shot.Unnecessary elevation of the butt of their cue on nearly all shots.
