Those players are all human. They do hit the exact spot on cue ball a much higher percentage of the time than the average person. They do occasionally screw up though. To say they aimed incorrectly is laughable. Something with their stroke due to pressure or they are really trying to force the cue ball. Maybe a lapse in concentration but it just won't be faulty aim.
Wrong again. (if it is 'laughable' it means you do not know how to aim consistently either). Maybe some instructions from a certified Pro like Scott Lee or Fran Crimini would help you understand.
Anyway............
An esteemed writer and seller of a book on how to "master aiming and never miss another ball" wrote his epic on
AIMING. If that was not critical, then why did he not write his book about stroke instead of aiming? I was told that not one word in that book was about stroke? Why not ???
In fact, this writer will say if you miss a shot..."that was a 5/8 ball fractional hit and you aimed it as a 1/2 ball hit or a 1/15 hit or a 3/8 hit".
Listen to what pros have to say..."I hit it too thick and it rattled"..."I overcut that ball and it was a simple half ball hit". This can go on and on...do they ever say "Oh my stroke was faulty"?
I would prefer to listen to what the pros have to say rather than dwell on inconsistencies from some half-baked amateur.
Of course, that is my approach to learning about anything....find the BEST at something and listen to what they have to say. Then do my dead level best to emulate it.
You will do as you choose, I already know that, so further back and forth on this is futile. In all seriousness, one of the certified instructors could really help you out.
Have a happy venture.
