[Yoda]

Imagine a rod from the base of your neck to the "tip of the
triangle", PP#1, the point where your hands meet

A swinger will rotate around that point (using horizontal hinge - rotation
point) and a hitter with "mirror" the wrist hinge at that point
(angled hinge)


You can see the 'rotation point' in the sequence of Clampett. Imagine that
line from the base of the neck to the hands, and you will see he rotates
around that point in a smooth motion

The center of the Left Arm Flying Wedge Rotation -- in both directions
-- is its Left Shoulder Hinge Pin. The center of the Pivot Motion is
the Stationary Head or, alternatively the described 'shirt label'
point 'between the Shoulders.'
