Mike - you wrote-: "Secondly, the Right arm can help the pull of the clubshaft (maybe passively versus "actively") (maybe directly or maybe indirectly) or as Homer Kelley stated at least "aid in the support of the left arm pull" 10-24-F 6th edition. So using accumulator #1 does not always mean that you are pushing the entire left arm and clubshaft as a unit (Primary Lever Assembly). For example, can you grab a club with your right hand only and pull it by straighteing your right arm? Can you pull an arrow out of a quiver along the shaft of the arrow with your right hand by straightening the right arm? Or as noted in 10-24-F - you can have the right arm push the left arm and as a result create more pull on the clubshaft."

I have great difficulty understanding your position. I thought that the definition of PA#1 release is that it must be ACTIVE and not passive. If there is a small amount of triceps action in the downswing that ensures that there is active extensor action (via PP#1) and a maintained sense of clubhead lag (via PP#3) then it doesn't imply that PP#1 is being actively released.

I also don't know what you are implying when you state that one can grab an arrow out of a quiver with the right hand and pull it down to the ball. That's obviously possible if one grabs the arrow with the right hand (palm and/or fingers). However, in a golf swing the right hand doesn't grip the clubshaft and pull - it can only PUSH at PP#1 and/or PP#3.

I don't have the 6th edition of TGM. If HK states that the right hand can push on PP#1 while the left hand pulls on the grip, I can easily understand that this is theoretically possible - but that doesn't mean that it is advantageous. If you look at the hand-drawn diagrams I posted, it can be seen that an optimised downswing pivot-action should optimally release PA#4 and maximise left arm speed at some point in the mid-downswing. Why would one need to add any active release of PA#1 to supplement an optimally fast left arm speed? Why add a push element to a pull element and complicate the swing by introducing a major timing problem - that any push by PA#1 must be perfect in both timing and degree of push force to complement the already optimised release of PA#4 and #2?

Golfbulldog - you wrote-: "I agree - tricky stuff. it would have to be 4, 1 , 2 , 3.... which would mean pivot throwing left arm off chest (right shoulder fly wheel)...then a bit of PA1 (using right shoulder as backstop brace off which to push) .. then 2 and then 3...."

That four barrel combination is theoretically possible, but it would only make sense from a practical standpoint if the downswing pivot action did not adequately release PA#4 and additional push force was needed from PA#1 to fully release PP#4. However, surely it is easy to get a full release of PP#4 from the downswing pivot action alone? Why would one want to add an additional factor and complicate the downswing by introducing a major timing element?
