actually i think he was finding his vision center but i am not an instructor or expert.He was simply reorienting his head to be more square to the shock. What is so unusual about that?
spidey i think patrick was describing a new consistent head position for him for all shots
i think the latest version of cte has looking at the cue ball differently based on the type of cut right or left
but i dont think there are different ways for your head position over the cue
i dont want to speak for patrick
but i think he was referring to how you look at the shot when behind the ball in the standing up position
