I see where you are going, Daryl. The last figure descibes the rotation of the Left Arm Flying Wedge in a horizontal hinging procedure.
That is perfectly True. You understand that.

No.. The LAFW rotates on one of three associated Planes. Horizontal, Vertical or Angled.

* A rotation that is on plane has a rotation axis that goes straight through the plane.
No..That's a Swivel, not a Hinge.
Hinging:
It is said that Hinging controls the Clubface alignment. It controls the Clubface Alignment to an associated Plane. Hinging is not what squares the Clubface for Impact.
Horizontal Hinge: causes he Clubface (and Left Arm Wedge) to rotate on a Horizontal Plane
Angled Hinging: causes the Clubface (and Left Arm Wedge) to rotate on an Angled Plane

Different words, and your way of saying this is perhaps more in line with TGM. But the point is that the LAFW is vertical to the swing plane at low point and parallel to the inclined plane somewhere in the upstroke. And the Hand club is supposed to be on plane at all times. At least for a swinger.
Nevertheless it's the rotation of arm and club on plane that matters when we discuss RPM and MPH.
This thread really good!
helps me rethink about rhythm.
I just know that the rate of my pivot turning on the incline plane ideal should be the same rate of rotation of the clubshaft in a counterclockwise direction on the downswing.
It often isn't and can be a bit slower or faster than the pivot RPM. How it mismatches together(can be done on purpose) can be used to hit a fade or draw.
