Martee,
I can't really explain the concept of the left wrist facing the plane- as it is not one that I use or originated. Nor did Homer use it in the book. Are we talking about the left wrist/palm exactly parallel to the plane?, or just a general term of generally facing the plane? Of course, that would apply with hitting also- the left wrist facing the plane. Does the hitter or swinger have their left wrist/palm facing earlier or later than the other? Depends on the player and his pattern. Generally speaking during the takeaway for a swinger who is setting up momentum in the club by dragging the club back- you're not going to have much rotation of the forearm at that point, until the hands slow down and the momentum of the club continues- and rotates the left wrist. The hitter would generally have rotation from the very beginning, created by the body/arm motion- not an independent or conscious rotation of the forearms. Likewise, the swinger doesn't conscious rotate his forearms but that occurs as a result of centrifugal force, anotherwords your loading actions and acceleration methods determine your wrist actions in the ideal situation, for both hitters and swingers. That's just part of understanding the individual components of the Golfing Machine and their role in relation to the broader concepts in the Golfing Machine.

Note I don't believe I advocated the rotation of the forearm, but of the wrist(which will if done will eventually effect the forearm).

What you wrote is exact the opposite that I was taught.

The uncocking of the left wrist should be a perpendicular motion (2-P) and when on inclined plane to maintain the clubshaft to remain on the plane face (2-F) that would require the palm to be facing the inclined plane as I understand it.

Given the 10-18 references (matches 12-1/-2 stroke patterns), I believe it is more than fair to say there is a turn both for the swinger and hitter.

Given the above two paragraphs, I would say Homer did use it in his book. Both a hitter and swinger are at the top with the left palm down and the right palm up.

I need to reseach out more why a swinger is completed so early but the hitter is gradual, like the body/pivot motion. The swinger in the downstroke uncocks and then rolls into impact (swivels). If the actions of the downstroke is opposite that of the backstroke (7-18 ), then for the swinger it would be a 'start up swivel' which would or should be completed before the hitter who is letting the it be as the pivot motion goes.
