I discover new flaws of my game and improvements on a pretty regular basis. Most recently I realized I had an issue with cue position relative to my dominant eye. I had also been paying attention to snooker fundamentals and picked up a couple other things:
1) Stance and eye dominance can have a very close relationship. Steve Davis (I believe) mentioned in a video that an angled stance suits a left eye dominant player while a squared up stance suits a right eye dominant player. I found this to be true because I am much more comfortable with left foot parallel to the shot line and my back leg turn 30 deg. or fewer from it. Mind you I'm not squared up like a snooker player but more like some of the European pros. This has helped a lot with shoot making and vision center consistency.
2) Pull back. Pull all the way back. For the life of my I couldn't figure out why there were some shots where I could draw the ball 15 ft but others where I could draw back from distance. Well I figured out my issue and it was that I wasn't pulling the cue all the way back. As a result all my power was created after the cue ball was gone and even with a "full follow through" something was missing. This also hurt my accuracy on some shots. After I started pulling the cue back all the way with various bridge lengths rather than various distances with the same bridge length my cue ball control, shot making, and action were much much better.
