[Yoda]

Sorry Yoda.. but I am not sure if that answers my question or not. Are
you saying the alignment is merely the result of either?

From what I know... and looking at 4-O... there appears to be only reference
to these movements based on hand motion only. This does not account for arm
participation. Yet quite clearly 4-C is only possible with a rotation of
either the forearm or the whole arm.


To me I would think a distiction between forearm rotation and entire arm
rotation would be a rather important subject to discuss when we look toward
what parts of the body are being effected by each stroke pattern.

As I've stated repeatedly in numerous posts, there is no true Rotation (of
the Left Wrist, Arm or anything else) in the Hinge Action. The Flat Left
Wrist -- and you can throw in the rest of the Arm if you want to -- remains
Vertical to the selected Plane of Motion. Only in the Swivel is there
a true, independent Rotation of the Wrist and Forearm.
