I really resent this constant use of the word "guesswork" from aiming system supporters. I don't know how other aim, but there is no guesswork involved in the way I make a shot. It's kinda like asking a concert violinist if he is just guessing when he jumps up to the fifth position and perfectly nails a note on a fretless fingerboard... ev-er-y frickin' time.
He isn't guessing, he just
knows the note is there, and he hits it spot on. Nothing else would be acceptable in the classical music world. When he began as a child, his fingers were all over the place, producing pure rubbish and a scratchy tone. Without frets to stop the strings precisely at the correct length, he must slowly learn over the course of thousands of hours - and with the scantest of references - exactly where each and every note on the fingerboard lies.
Over the years, our little prodigy morphs into a masterful player... one bad note at a time. This is what I mean by "feel". And don't mistake the fact that the fingers are touching the fingerboard, and so, provide the feel through actual physical contact. That's not the feel I am speaking of. Rather it is a type of biofeedback that takes place between the fingers, the bow, and the ears. This same type of feedback is at play when someone learns to play pool by feel (HAMB) - a mere neural loop between the stroking arm, the eyes, the brain, the CB, and the pocket. And it can be just as dead-on as the concert violinist's notes are.
BTW I hate the word "feel" for this phenomenon because it is often (conveniently) misinterpreted as having a physical connection to the balls, which of course, is not allowed. I prefer "judgment", "intuition", "table sense", or even CJ Wiley's (a definite feel player, like many top pros) "Kentucky windage". Unfortunately, I didn't invent the nomenclature used by pool players.
Oh... I'll start the list for you. Lou Figueroa is without a doubt a feel player. Your turn.
