Although there is no question in my mind as to the outcome, the way to
prove this is not through mathematics, but through measurements.
By measuring the force x distance applied to different paddles when
propelling a particular boat at a particular speed, one could answer the
question definitively. Unfortunately, the instrumentation required for
that would be fairly complex, and may inhibit normal use of the paddles.

Another way of measuring it is through oxygen uptake of the paddler
under controlled conditions (same paddler, same boat, and same speed).
That would factor in not only the work applied to the paddle, but any
secondary/ergonomic effects on the paddler. I think the instrumentation
is simpler, and it takes all effects into account.
Is anyone on the list familiar with current techniques for measuring
oxygen uptake?

I agree, though, what we need is a comprehensive source of paddle 
physics and hydrodynamics backed with lab data.  AFAIK, this doesn't 
yet exist.  Some very ambitious soul has to go thru the mountains of 
publications and accumulate and summarize the info that's out there.
Volunteers??  :-)
