Hitting and Swinging are alternative Loading Actions.

The Right Shoulder is Part of the Pivot. Although the Right Shoulder is not an Accumulator, it is a massive source of Power. Accumulators are out-of-Line conditions that add mechanical advantage while moving from an Out-of-Line state to to their In-Line state.

The #1 Accumulator adds mechanical advantage to the Pivot because while the Right Elbow Straighten 6 inches, it causes the Clubhead to move 24 inches. It has the same effect as a "Pulley". A Pulley is a form of Mechanical Advantage.

Power Package Accumulators add mechanical advantage to the Power generated by the Pivot.

The #1 Accumulator may be the sole source of Power for Short Shots.

Yes, the right shoulder is part of the pivot, but since it is braced in the Hit, it isn't spun. If it were, #4 would be one of the Hitting Accumulators, but it is not.
