I can understand the right arm pushing the lever assemblies only as occurring in two ways - the right arm can push against PP#3 and/or PP#1.

I thought that if the right arm pushes against PP#3 using an axe handle technique (radial direction) that it represents hitting. If it represents hitting, then isn't this "right arm pushing the lever assemblies" a power stroke? Why does he call it a trigger? Also, doesn't the push action occur, from a biomechanical perspective, from the active straightening of the right elbow via active right triceps action - which is an active release of PA#1? In other words, how can this "right arm throw" action be a trigger and not a power stroke (due to release of PA#1) if the golfer is hitting.

Jeff,

Of course, as in your quote above, if the golfer is Hitting ("radial acceleration / axe handle technique"), the Right Arm Throw Trigger is prelude to Right Arm Thrust through Impact and does indeed ultimate in a Right Arm Power Stroke. However, my response was to your premise as postulated in your Post # 30 above (which mandated Swinging):

"Then his right arm throw action induces a passive release of PA#2 via centrifugal action (rather than an axehandle technique of radial force being applied against pressure point #3)."

And this is a Swing -- by your own definition -- with a Right Arm Release Trigger.
