Then why does the first sentence of 6-B-1-D say..."EXTENSOR ACTION is exclusively the steady effort to straighten the bent Right Arm"???

[Bold by Yoda.]
Because that is what it is, DG: The steady effort to straighten the Bent Right Arm.
But, alas, the Left Arm Leash constrains the unruly Bent Right Arm, and hence, despite its best effort...
Until the Left Arm moves away from the Right Shoulder in the Downstroke...
The Right Arm cannot even begin to straighten.
These comments seem to contradict Tomasello's explanation of Extensor Action???
DG
Please provide any conflicting Tomasello version, DG, and I will be happy to comment.
Meanwhile, suffice it to say that the normal condition of the Arms (6-A-4) is that the Left Arm is always Straight and the Right Arm is always Bent until the end of the Follow-Through (Both Arms Straight position).
