thanks for putting up this thread.
The brain-computer we all have working when we are shooting is a black box, we don't really don't know what's going on in there, but routine is clearly a given when we are talking a target sport that requires still objects being moved toward a target. Hand/eye coordination would seem to benefit from a small extension of quiet eye target perception time, but obviously you wouldn't want to stare at it; flow, rhythm, stillness all of these are involved in golf, archery, riflery, billiards, etc. Finding the right combination of all of these so that you're "in stroke" so things become automatic is I think what probably fascinates us all.
I've always wanted to ask Dr. Dave if he had ever come across any studies looking at improvement in hand eye coordination for players who had dedicated to playing with their offhand for some amount of time every practice session. I think it would be interesting to look at.
