>>> My particular interpretation of Jack's theory is as a 3 arc model.Hips as one arc,shoulder/arm/hand as second arc,bathead as thrid arc.Torso/body twists between hip and shoulder link.<<<

Hi Tom

You are correct in saying I have a 3 arc model. I mentioned 4 axis of rotation to accommodate linear mechanics. However, with rotational transfer mechanics, axis 3 (lead-elbow) is not a factor. The three arcs of my model is the result of mechanics that synchronize the angular displacement rate of the shoulders, hands and bat-head.
