Phil- You put it to the point dead center. No wiggle room there, except of course the perpetual motion machine I invented in my basement. Cheers, Dave in MT

Sorry, Mike, the frame will never return as much energy as is put into it.
Some heat is created by the flex of the frame. How much? One hundreth of a
degree? One thousandth? Don't know. But you can never recover all of what you
put in or else we'd have perpetual motion.
