I'm pretty sure we're on the same page . . .

I'd like to think so.

I am learning a lot from your posts.

(But I still think I understand ordinary machines better than golfing machines though.)

but how would power from the pivot be transfered from the pivot to the power package/lever assemblies in points other than pressure point #4? Would you say there are some points missed in the right arm? if we are restricting our discussion to the power package (arms hands club) as Mr. Kelley defined it?

Structural support and aligments are key here. G.O.L.F: Geometric Oriented Linear Force. It is the linear forces that produces swing speed. The radial forces (the pull from the swing center) only changes the direction. The right side delivers linear forces through pp#1 and pp#3, weather the work is done by the pivot alone (swinging with extencior action) or also by the left arm as in a hitting stroke. Of course pp# 4 delivers linear force too by pushing the primary lever.

Even pp# 2 delivers linear force. Not linear with reference to the primary lever but with reference to the swing center. If the right arm was hanging from the neck it would only be able to deliver radial force. But luckily for us it is attached to the shoulder and is therefore pulling the club with an offset from the swing center. So as long as we're driving that pivot...

I think you nailed it with your quote of DEFINITION and STRUCTURE above.
