With Zero #3 Accumulator, there is a Left Shoulder Plane Angle. And all three Hinge Actions (Clubface Motion through Impact) produce an identical amount of Clubhead travel (to the end of the Follow-Through / Both Arms Straight position).
Good place to start . . . Zero . . . and move up from there.
Question: With Zero #3 Accumulator, the travel is all the same for each Hinge Action. So with increasing amounts of #3 Angle are is the rate of closing and lay back slower for a given amount of Hand Motion since the travel necessarily increases?
