It occurs to me that Basic Motion includes the study of the Primary Lever and the mechanics of Hinging. So, the Left Arm moves independent of the stationary Pivot. If the Left Arm is glued to the torso, then Hinge Action isn't available.

I'm not sure what this means (big surprise). I haven't said anything about the left arm glued to the torso, have I? BTW I thought the left arm is just like a lifeless string (or a belt like Yoda shows in his Golf Channel video) which has no power and movement in itself, but is controlled and moved by the right arm and elbow in the takeawy and backstroke up to the top - but this is perhaps something else than what you are talking about? But if you want, you can try to clear this up for me.
