You know that you could bypass the complicated assessments of sequenced releases by becoming a Hitter. We've got it so easy. I'm a simpleton; therefore, I'm a hitter.

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.

Hey Ted

Your right, the left shoulder does moves around in its own orbit but that is moved by basically yet another another sphere with the point between the shoulders, or the stationary head as its center. My spheres analogy is basically the usage of a center point and the circles of rotation that influence it. This is exactly what Homer used, but in a slightly different way - for him it was hinge pins and swivels which influence a center point to demonstrate the same axis of rotation. For example the end point of the radius of the left arm (hand) if not restricted by anatomy or anything else could touch anywhere inside a sphere with the left shoulder as its center.

With 1-L the hinge pin is fixed to a stationary post per my 1-L and 2-K equivalent animation, however in real golf with the shoulder motions, the axis of rotation or 'the circles' of that sphere stay exactly as they where whilst being moved with the orbit of the left shoulder around the head as its stationary point which is ultimately controlled with the right shoulder. So basically the 'left shoulder is moved in the sphere' around the head (which is a moving chord from a radius inside the sphere if the head is taken as the center rather being a purely a diameter when the point between the shoulders is used) but the orientation and the circles of the sphere doesn't get influenced by its own local movement....the vertical plane dictated by the hinge action doesn't not change regardless of the shoulder moving....

All about centered arc . I know we're for sure we're not in disagreement though - just its me not explaining myself enough...lol

Ps wait until you see the new animation when I finish it, its going be wonderful .
