I believe that the hands and clubshaft can be on the turned shoulder plane even though the left arm is not.So I suppose I am saying that the plane of the left arm flying wedge is not the same as the inclined plane but the hands and clubshaft are on both-they intersect at the hands-the #3PP.

I agree that both planes intersect at the #3 pressure point. But the Left arm flying wedge requires a flat left wrist so that the clubshaft, wristcock, and left arm lie in the same flat plane.

You agree they intersect which implies two planes.
