Jack-

I think motionanalysius would be good at getting at this with the perspective that mechanics are much as you describe them with certain predictable variation that goes along with pitch location.

Certainly we want to see the seqeuntial acceleration/deceleration of segments with associated migration of the swing axis and the "sped gains" seen with Zig's equipment for example.

I would think that in the case of inside/high ball the head would come more forward to set axis and shoulders would turn more with central axis. Outside/low ball, head stays back and swing might have more off center axis. Field studies might be good to sort this out.
