What is a 'micro-stroke'? Why would you want to use a micro stroke?
When I'm playing my best, I don't even look at the cueball after setting my to on the table. I take 0-2 practice strokes generally.
So much of the recommended psr stuff is just noise that interfers with playing well. Minimize the psr to the only things you need. See shot, align cue, relax, shoot. That is all you need. It isn't helping to chalk exactly six times, inspect the cueball, shake your left leg, shrug your shoulders, bob your head, etc.. See shot, aim shot, shoot shot.
