At impact fix, you have a bent right arm still, you have not 'fully extended'
At fix, the proper extension is DOWN UNDER THE GROUND, in front of the ball,

Lever Extension (2-P) is a Left Arm and Clubshaft concept. It
is not at all dependent on Right Arm Extension. In fact, in the best
Strokes, Full Extension of the Right Arm does not and must not occur
until well after Full Extension of the Primary Lever Assembly (Left
Arm and Club).


Bottom line: Even at Low Point -- which you continue to define as being under
the ground when in fact it may be on or above the ground -- the
Right Arm is Bent. It is only at the of the Follow-Through (8-11) --
which occurs well after Low Point that both Arms are straight (6-A-4).
