[O.B.Left]

VELOCITY POWER

6-B-2-0 THE SECOND POWER ACCUMULATOR When the Left Wrist is Cocked (in excess of the selected Clubshaft-Left Hand Angle (6-B-3) in the Address Fix positions) it forms the Second Power Accumulator. It’s the true Velocity Accumulator because of the shortness of its travel time (during a Maximum Delay Release). Centrifugal Force, Accumulator #1, the muscles of both forearms, any – or all – are available to actuate this Assembly. Its “in-line” condition is FULL EXTENSION as determined by the Accumulator #3 requirements – if any. It is the “Downward” (Angle of Attack) Motion per 2-C-0 and 2-N-1.

Actuation is the triggering of #2 IMO, like a tipping point if you will for the Swinger. Non Auto Release Trigger. You'll notice Homer doesn't list wrist muscles ,active hand unbending etc . A Left Wrist Throw is not done by the wrists.
