Thanks for letting me aboard & i'll check out your link

It sounds like Daryl is suggesting that we keep
"the Hinge Action (2-G) of an Angular Motion (2-K) operating on an Inclined Plane (2-F)"
in mind as a corner stone of our knowledge about TGM.
My understanding of what he is saying so far is
Hinge Action - the way the left arm hinges at the left shoulder & this is the place where the angles release
Angular Motion - is the angles created by the wrists & club & also the right forearm & upper arm. The 'motion' being them going from angled to straight at the low point of the swing.
Inclined Plane - being simply that we are bent at the waist when we perform the golf swing giving rise to a plane that is like a pitched roof

Sounds like you have a lot of talent for this stuff. But you must get Daryl's approval first.
