Just some thoughts. Plane Angles are alignments, not positions.

A three dimensional impact occurs when the Clubshaft revolves end over end and travels on that same plane. If you grabbed the grip of the club and throw the club so that it revolves end over end, it will seek to revolve in its own plane. Plane Shifts are hazardous. Any golfer that downshifts to the Elbow Plane should first drop the Clubshaft onto that plane. If not, you'll still have Impact, but not three-dimensional because the Clubshaft is jerked off plane.

Homer Kelley's Power Package has the Right Forearm Flying Wedge (Bent and Level Right Wrist) control both Alignments (end over end and within the same Plane). When the Right Shoulder Moves, it moves the Right Elbow. It must move the Right Elbow on the Plane of the Clubshaft so that the Right Forearm can support the Clubshaft through the Release and Impact intervals. Then, the Shaft will remain bent (stressed) at Impact.

So, the Alignment of the Clubshaft at the Top of the Backswing should be Pre-Aligned with whatever Impact Plane Angle you’ve chosen.

The Plane is whatever Inclined Angle the Clubshaft is revolving on. If you adopt the "Power Package" structure of the Golfing Machine, then according to the Theory, the Right Elbow will be On Plane when the Hands and Right Shoulder are On Plane. Actually, the Power Package has the Hands, Left Arm, Clubshaft and Right Elbow and Right Triceps muscle control the Right Shoulder Location. Then, design a Pivot to Push the Right Shoulder Down that Plane while allowing the Right forearm to be On Plane during the Release and Impact Intervals.
