Yoda - thanks for replying.

I obviously cannot really understand the difference between triggering a release and powering a release - especially with respect to a "right arm throw".

I am reading 10-20-B and trying to understand what is meant by a "right arm throw" trigger. HK states under 10-20-B that "the right arm simply pushes the lever assemblies towards impact -- usually restricted to hitting."

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.

Another question - HK states that the "right arm throw" is restricted to hitting. However, I thought you implied that a right arm throw (which is defined by HK as a push action of the lever assemblies towards impact) can also be used as a trigger to release PP#2 in a swinger's action. This puzzles me. Where is the "right arm throw" exerting its push action when triggering the release of PP#2 in a swinger's action - ? PP#1? If a push force is used against PP#1 in a swinger's action - how does it trigger the release of PP#2?

I also do not understand TT's right arm throw action. He states that a golfer needs to throw from the top and that one should actively drive the club down-and-out. My only mental conception of what a "right arm throw" means from a biomechanical perspective = an active extension of the right elbow via active right triceps action. TT does not state how that right arm throw action propels the clubshaft. From my perspective, it can supply a push-force at PP#3 or PP#1. If it applies push force at PP#3 on the back side of the clubshaft, that represents hitting. However, TT is talking about right arm swinging. Therefore, I presume that he is referring to the right arm applying active push-pressure at PP#1. If one applies active push-pressure at PP#1, then its effect must surely be to propel the left hand to move faster. That's normally what the release of PP#4 does in a pivot-driven swing. However, TT doesn't state that one activates the pivot to release PA#4 and move the left arm/hand forward. I therefore concluded that TT meant that the "right arm throw' pushes the left arm/hand forward as a substitute for the release of PA#4. However, you indicate that the right arm cannot perform this power stroke role in a swinger's action - I am therefore very confused.
