Here is a series of images showing the release of PA#3 in Tiger Woods swing.
One cans see that both PAs 2 and 3 are releasing.
Although PA#2 must sequentially release before PA#3 in a swinger, HK states that they can overlap. What determines the degree of overlap of the release of PA#2 and PA#3? Does the position of the right elbow and the position of the right forearm (degree of passive release of PA#1 at every particular time point in the pre-impact phase of the swing) determine the degree of overlap? Should a golfer consciously control the rate of counterclockwise rotation of the left forearm during the release swivel phase of the swing - so as to affect the rate of release of PA#3?
Why did HK refer to PA#3 as the transfer PA? The word transfer implies the transfer of power without any independent production of power. Do you think that in Tiger Woods full driver swing, PA#3 is independently responsible for the production of significant swing power (relative to PA #4 and PA#2)?
