D, where does Homer say that the Aiming Point Concept cant be used by golfers who shift planes on the downswing? I get your logic but.......I can see it the other way too.

Actually, Homer does lead one to believe that the Aiming Point Concept Can be used with Plane Shifting.

See the Second Paragraph below.

10-23-B ANGLED LINE This pattern is used with the Plane Angle Variation that include a shift to (or back to) the Elbow Plane during the Downstroke.

From the Top-of-the-Straight-Line hand position the Hands take a nearly vertical path to the Plane of the Elbow Angle before they start their drive directly at and through the Aiming Point (2-J-3).

On the other Hand, he talks about the "Aiming Point Equivalent" for Plane Shifters is the "Open" or "Closed" Stance.

The Aiming Point (6-E) equivalent for this procedure is the “Open” and “Closed” Stance Line (10-5) which varies the Ball location in its relation to the body for any given Release Type (10-20, 10-24), to compensate for different Clubshaft lengths and must worked out by experimentation (See 9-1-1) because the players habitual Pivot procedure will bring the Hands very dependably into Release Position at the same time point in relation to the body.. So then, of course, errors in the Pivot affect the results adversely. As with any Swing Release (10-19-0), Ball placement (2-N) depends on Clubface alignment design (6-B-3-0) as well as Hinge Action (2-G). Right Arm participation must be per 2-K and 2-M-3.

I don't think this to be a contradiction. I do think that HK thought is possible to choose one or the other but that using the Aiming Point is more or less a Translation into learning the Straight Line Delivery Path and Hands Controlled Pivot. see below

The Pivot may be educated to produce geometric Hand and Club alignments and relationships with some degree of precision which definitely improve control. Expanding this infiltration could serve as your “Relative Translation procedure (3-B) to true “Hand Controlled Pivot” procedure. But – except as a temporary Band Aid, any mandatory Component position or location can only be disruptive and carries a prohibitive price tag. See 1-K.
