[Yoda]

The radius IS constant. You have a circle, you are inside that circle at all
times. You position that circle relative to the ball and ground to ensure lag
at impact and downward contact (well BEFORE full extension - before full
extension of the lever assemblies)


[Bold by Yoda/Yoda.]

First, or the record, there is only one Lever Assembly, and that is of
the Left Arm and Club. The Right Arm drives that Lever Assembly
(actively with Hitting or passively with Swinging). It is not a Component
of the Lever Assembly.

Second, please explain why your Theory demands that both arms be
straight. The geometrical concept of a radius is one straight line --
not two -- from the center of a circle to its circumference.
