Mike,
On a more serious note the first post of the thread takes vision apart into pieces and lets you understand some things about it and you end it by simply saying....that its probably good to let vision do its work.
I agree. A few weeks ago someone posted a link somewhere to a Snooker site where the guy coached snooker players on their aiming. The link was awesome.
This guy took a mirror and taped up and covered everything but a small strip down the center and set it opposite a pool table behind the side pocket.
Then he put a camera on the opposite side and he had two players come in and get into shooting position to pot a shot in the side pocket.
The camera revealed how player #1 let his head move to the side before settling into position. Then he did player #2. Player number 2 went perfectly down into position and illustrated what he wanted done. Then he cross blended the 2 players and you could really see how far out that Player #1 was.
I had been having some trouble on selected days then had days everything was perfect and I thought on this for a long time.
The minute I made myself go straight down into the shot regardless of whether or not I was set up right, my game went up. If I was too far out I would just get back up resight my shot and get down again closer to perfect, make micro adjustments and let it roll.
The visual adjustments as you point out I found to be the first line of defense against a missed shot. If you are not visually aligned first your body will be contorted into a forced alignment as you adjust instead of a natural down position where everything is set, solid and more comfortable. I personally noted that when gross adjustments are made the body has to do things and this affects the shoulders which are attached to the body and then its possible to get your stroke swing off of a perfect line.
I will try to post the link if I can remember where I saw it.
Great post and great point.
