Could variations in the degree of downplane right shoulder thrust affect the amount of clubhead speed loss during impact due to ball collision, and the amount of energy imparted to the ball for a given clubhead speed and a given amount of forward shaft lean?
Consider a swinger's action. The release sequence is 4:2:3. The club reaches impact due to the passive release of PA#2 which is a CF-induced action. The right hand must keep up to maintain clubhead lag through impact. The right arm straightens passively in the downswing, but there must be enough right triceps muscle contraction to allow the right arm to straighten enough to allow the right hand to keep up with the left hand and maintain a bent right wrist/FLW through impact. However, straightening the right arm may not be enough if the right shoulder socket doesn't move forward enough downplane to support the right arm - so that one doesn't run-out-of-right arm. The more the right shoulder moves downplane, the more bent the right arm can be at impact. I am thinking of Hogan who had a very assertive pivot rotational action that allowed him to drive his hands inside very quickly post-impact, and that is presumably due to an actively driving right shoulder downplane. Could that driving right shoulder add thrust power (drive loading power) to the right hand at impact (passively via the bones of the right arm/forearm/hand) and thereby increase swing power at impact - even if one is a swinger?
