Thanks for your post, BerntR. Once again, I want to respond to this very important point.
1. The Clubshaft has inertia. Tipped-stiff or senior flexible, it has inertia.
2. At the same time, Centrifugal Force has a Line of Pull. That invisible line is from the #3 Pressure Point (first joint of the right forefinger) to the Sweetspot. This Lag Pressure Point Pressure (1-L #7) is what is driving the Club, not the Clubshaft.
3. The inertia of the clubshaft cannot keep up with the Centrifugal Line of Pull. Hence, it lags behind. This 'reverse' parabola (reverse in that the forward bend is counter-intuitive) made a dramatic appearance in Ben Hogan's first book, Power Golf. With the exception of Elbow Postion (Pitch versus Punch), the photo on page 97 of that book (hardcover version) is virtually identical with Image #2 (below) in your post.
If somebody could put that up, I'd appreciate it. Thanks!
