I was told by one of the coaches, and possibly by someone in this group too, that when we kick on
the backstroke, we tend to use more muscles, pushing up as well as down, where in freestyle kick,
largely due to out psyche, we tend to exert the muscles only one way. This would be in addition to
the observations that you made, about the geometry and the body position.
