The Inclined Angle of a Plane varies with its reference point. The #3 PP should follow this Inclined angle while tracing the base line of the Inclined Angle.

Who thinks that the Clubshaft should lay Perfectly Flat on the Plane throughout the Swing?

How many think that the Clubshaft will be off by a few degrees if we comply with the Left Arm Flying Wedge?

I have not seen any video of someone keeping the shaft on plane throughout the swing. There is always a shift. If you stand in a Homer Kelley type plane board you would understand why or why not.

Actually the line formed from the grip to the sweetspot should lay on the plane. Not the shaft.
