Great post again O.B. If I may add one note.

This first few feet of Hand travel in Startup which J.R. describes, a travel motivated, produce solely by the Hips clearing from their Fix position: Some would might say "Ah, but surely that's Pivot to Hands".

To which I would say; "Not necessarily, Buster. IF you're Tracing, with your mind in your Hands .....its still Hands to Pivot".
The same deal happens in Startdown when the Pivot takes the Hands Down the Inclined Plane for the first wee bit. The Pivot may be driving the car but the Hands are back seat driving, directing.

I think there now is some confusion about what starts the backstroke (start up) - is it the right hand/right forearm or is it the hip (in a right-left foot action in a coordinated way)? Maybe this needs some more clearing up?
