I find that 10-18-C description very interesting and very new to me - as it implies that there is horizontal/angled/vertical hinging actions in the backswing. I cannot understand this biomechanical phenomenon. Does HK describe the biomechanics of backswing hinging actions? I can understand the followthrough hinging actions as being due to a variable degree of external humeral rotation happening at left shoulder socket level, and I can conceptualize the biomechanical process.
However, what is happening biomechanically if hinging actions are actually occurring during the backswing?

This is the reason I discussed hinge action and when "should" (I know there are no options...) an intended hinge action make it's presence known in the golf swing.
Homer was always keen on backswing feels mimicking downswing feels...snap load with snap release.... takeaway swivel with release swivel....the same can be done with hinge action it appears - no?
In the Cuscowilla homecoming thread several people saw Yoda and Golf Guru do full swing vertical hinged 6/7 iron shots....somebody asked if they did a "reverse roll"/vertical hinge in the backswing (ie. hinge action "prep feel" in the backswing) ....the replies did not apear to deny this action.
If, as some of the science TGM investigators appear to be saying now (as I understand it = Dr Zick for TGM ?) Hinge action actually starts to occur on the downswing then it would appear sensible to start prepping that feel on the backswing ( snap with snap etc...) - no?
Has anybody got any 3D analysis (with back up trackman data) to show that a swinger with intended dual horizontal hinge has the same downswing as a swinger with dual vertical hinge?
As wrist action is intimately connected with pp3 location and loading for swingers....and that is related to aiming point...I hope this is not too much threadjack....sorry!
