Hello HCW, I replied to Slinger with a bit about my background and I reply to you now with thanks for the clarity you provided regarding supination and pronation. Rarely is the word supination mentioned in the annals of golf instruction yet if both hands are holding the club snugly, pronation of one forearm will be simultaneously accompanied by supination of the other and vice versa. I've always observed however that forearm rotation independent, beyond, and faster(rpm and mph)than whole arm rotation succeeds only as a corective measure or remedy for an off plane near the top, at the top, or start down off plane condition or it serves great purpose through impact for specialty shots. Actually forearm rotations can serve or disserve a golfer in so many ways that I don't feel my language is adequate to describe what I'm trying to convey. Anyway, thanks for the clarity and rare addition of the term "supination" in golf lexicon.

i don't have the book with me but as i recall in the picture definitions turning is pronation of the lead forearm and supination of the trail...rolling is the opposite...this is the basis of Accum#3 action (IMHO) while the whole arm rotation of the lead arm you describe is the basis of Accum#4 action (again IMHO)...
