You must forget about the Clubshaft Plane. If for no other reason, the Clubshaft simply cannot stay on it.

As the Sweetspot moves Up, Back and In On Plane, the Shaft rotates off its own Plane and onto the Sweetspot's Plane. For Swingers, that Rotation is accomplished during the Start Up Swivel. The Clubshaft then remains on the Sweetspot Plane during the remainder of the Backstroke and also into the Downstroke until the Release Swivel once again rotates the Shaft around the Sweetspot and back onto its own Plane.
