Absolutely agree, the arm do nothing without the loading from the legs and core.
But i still on my idea the trunk doesn't have volountary to drag. It musn't rotate as fast as possible.. legs haven't to work in that way during the forward swing.
The shoulder joint have to move at exactly speed needed by the arm... not less... but not more... because the dragging doesn't add power, but by me, destroy the arm coordination.
