But remember, guys, the Elbow Plane is not an absolute. Some Angles are steeper than others, especially through Impact (versus Address).

These steeper-than-normal Elbow Planes can approach the TSP Angle and, in fact, remain on it. In which case, there has been Zero Shift from the Top. One example is Brian Gay.

Thanks for this Yoda Ive been wondering about that one. The later editions definition of Elbow Plane got me mixed up.

How bout the TSP is it a range of angles too?

Would I be correct in thinking that though a Rotated Shoulder turn "can locate a TSP angle" its unlikely to be able to locate a TSP angle that is also an Elbow Plane angle? Is this one of the reasons for your preference for "Flat back", Standard Shoulder Turn?

I know this is slightly off topic but ..........since we're talking all around this lingering question of mine.
