Like you, I am a huge fan of 1-L. I think if instructors truly took the time to immerse themselves in the study of the 21 basic concepts, they'd be better teachers. Though, there are some logical limitations in the drawing.

In three-dimensional Euclidean geometry, a sphere is the set of points in R3 which are at distance r from a fixed point of that space, where r is a positive real number called the radius of the sphere. The fixed point is called the center or centre, and is not part of the sphere itself.

Since humans have to hit the ball, we have a center working around a center. The left shoulder and it's distance away from our Stationary Post make the fixed point no longer fixed. Hence, a spherical shape cannot truly exist. But, as Homer said about golf, "demanding that golf instruction be kept simple does not make it simple - only incomplete and ineffective." This applies to three dimensional geometry as well.

We can both agree in the spherical geometry, if we see the left shoulder as the "fixed" center. But, we must also see the center's movement in three dimensional space. With this in mind, we can't even get an oblate spheroid, similar to the Earth's shape, because even this has a fixed center.

I appreciate your drive to understand more about this subject. Even more than that, I appreciate your drawings. They are priceless.

So we have a whole construct of spheres now of the power package

The left shoulder - primary lever assembly
The left wrist - secondary lever assembly
The stationary post or point - either head or point between shoulders
The right upper arm - equi-distance either directly from the left (point between shoulders) or at opposite end of a chord from a radius (head).
The right wrist - working in conjunction with the left....

Oh and if your 'kuykendall' you may want to add the left elbow too...lol

If you look at the right arm structure - there is a basic geometry to it - if you draw a line directly from the hand to the right shoulder - the right elbow is always going to be halfway, forming an isosceles triangle on a plane. The obvious statement would be the closer the hand is moved towards the right shoulder the more the right elbow bends....
