I am viewing these photos with the red line emphasis and listening to Mr. Kelley's comment that the pictured plane is the clubshaft plane but the one we are working with is the sweet spot plane. Should one "program" these photos with the expectation that it will benefit clubhead control?

Actually, with the dowels, the Sweetspot is at the base of the dowel. When you point the dowel you are pointing the Sweetspot, so there is no conflict of 'Clubhead' and 'Clubshaft.' But let me extend your question to the Geometry of the Stroke Mathew has illustrated.

Clubhead Control (Lag Pressure) is assigned to one of the Pressure Points in the Hands (1-L-B), usually the #3 Pressure Point (right index finger). And Clubhead Lag Feel is Sweetspot Feel, not Clubshaft Feel.

The player monitors the Clubhead (and its Sweetspot) by Lag Pressure Feel only, never directly (5-0). That includes its On Plane Line of Flight (2-N-0). Thus, the On Plane Geometry of the orbiting Sweetspot is likewise assigned to the #3 Pressure Point (as guided by the Right Forearm's Tracing of the Straight Plane Line per 5-0).

It is that On Plane Geometry that Mathew has so beautifully illustrated and that students should find quite helpful in their efforts to Drive (Hitting) or Drag (Swinging) the Club Down Plane to Full Extension.
