ok, then how does staying flat fit in with what yoda just said:

"In the Backstroke demonstrated in the first three photos, a Plane Shift does indeed occur. The Club begins its journey (to the Top) on the Elbow Plane and then gradually Shifts to the Turned Shoulder Plane."

...ie i can't visualize how it can "gradually Shift" AND stay flat...abrublty shift maybe...i'm not saying one can't swing this way, just that i can't see how it can be on a "flat, inflexible, Inclined Plane"...but i'll incubate a bit more...

On the BS, when the shaft moves continuously through space from the elbow plane to the turned shoulder plane it traces a curved surface - a section of a truncated cone.
