Guess we do belong in the lab. The idea that CF has anything to do with clubface is in the 80%. The clubface is the "back of the hand" period. CF tries to align the COG of the club but on the selected hinge alignment is mechanical. As in "my "B" above.
I don't realy care what others do or think- It is their game - but I am comfortable with the physics.

I'm trying to understand you. It seems that you're mixing different concepts or maybe its just me?

Do we agree on the following?

Throw-out Aligns the Hinge. Throw-out forces the Hinge pin to become vertical to the Horizontal Plane. So, Throw-out causes the Clubshaft and Clubface to move along the axis of rotation to a vertical Hinge Pin. COG is Clubhead and is controlled by the secondary pin.

I'm not following your point about the Flat Left Wrist. If the Wrist was Turned through the Grip it wouldn't affect the Alignment of the Throw-out reaction. Throw-out can only produce a Closing Only Alignment (Horizontal Hinge).

Aligning the Clubface to a Flat and Vertical Left Wrist has advantages but its also the most difficult and demanding and you must always play at Low Point and its not always where you think it is.
