I think some are putting the cart before the horse when they say that there is more to playing well & improving than just aiming.
The thing is that many that have been mentioned already have those other things & hence IF they improve their aim with what is supposed to be an objective method then they should not miss after CTE that shot they would have missed before & that should result in more wins, no question, & a move up.
You say you have been playing for 45+ years, are a self-proclaimed expert on every topic on here, yet you have no clue why your statement above is pure poppy-cock? Guess you have never seen the B players that rarely miss, yet can't run 3 racks because they can't play position worth a lick.
Also, no one stated that improved aiming won't result in more wins. I did state that just improving aiming won't necessarily move one up in level. If that were to be true, then one could easily state what 5 steps are necessary to move up each level to pro (AAA) Since one only has to learn one thing to move up a level.
Since everyone starts at a D level, you then have C, B, A, AA, AAA. 5 levels of play. Since you want to equate aiming to moving up to another level, which level would that be, and what are the other 4 things one must learn to move up to pro? Must be a real easy game to learn if there are only 5 things one must learn to be a pro.
Or is it simply that your argument above holds no water?
