Tiger's head moving back and down does not affect his swing? Or do mean you can't tell from the ball flight, as in, he hits it good even though he makes this move? Surely, it has a effect, for which he must account.
Instead of centralized pivot center, what if we thought of it as point that the power package moves around? If we don't bob or sway the point between the shoulders, we don't have to compensate for that movement.
Nice one Henny
That blue dot doesnt move very much but for him to be perfect he must compensate for whatever movement there is, however small. As the blue dot moves so does the left shoulder, the levers fulcrum, the radius etc.
Jeff, I dont think Vj mentioned pivot center either. (Just got my vj book back). Again VJs "axis of rotation, TGM's "pivot center". They are different but related.
Consider this then, in your drawing above. Cant you see the blue dot or there abouts as being ideally stationary, centrally located and the yellow line as being VJ's axis of rotation, its bottom being left, near the left foot? The COG over the left foot , axis tilt, via a "Hula Hula Flexibility", which tilts the shoulders, which allows the right shoulder to move down plane. This axis tilt as shifting the axis of rotation from vertical to diagonal from a front on perspective. The down the line perspective showing the inclined plane and forward leaning axis of rotation. Need some 3D modeling maybe.
Page 53 of Vj's book figure 22. The axis of rotation is tilted diagonally via axis tilt and runs from a centrally located pivot center to the left foot.

OB
That is a very good image. And that axis deal hits behind you further down plane for different type of patterns . . . .I'd say the further downplane the more draw bias.
