Dear nfreeman,
You misspelled ophthalmologist. I was the subject of a witch hunt in Arizona because of my family connection to my father-in-law, Charles Keating. I stand on my record of caring (well) for over 100,000 patients and left Arizona gladly because I was clearly not wanted there. Life isn't fair. What does this have to do with swimming or physiology again?

PS I am still happily married. Are you?
I'm not an ophthamologist, but I can do 'rithmetic. 100,000 patients over, to be generous, 40 years is 2,500 new patients per year. That's about 7 new patients per day, 365 days per year, for 40 years, not to mention some 50 linear feet of folders added every year. You really want to stand by that claim?
I'm also not a hydrodynamic specialist, but I think you are confusing torque with drag, when you speak of the difference between a straight arm and a bent arm. If the surface area is the same (and they are in both instances), then the
drag will be pretty much the same (unless one position is much closer to the body and changes the hydrodynamics). The
torque will, of course, be more on the extended arm as measured at the shoulder, with force x distance and all that. In any case, when during the pull and after the catch does the arm present a forward velocity
relative to the water? I'm thinking never, because that would indicate no drag thrust backwards, and no forward propulsion at that time.
