I heard that TI is based on the research of a Russian scientist. Is this true? Who was it? Any published papers or data?
Thanks.

There's another way to think of this, though. If you want a full extension out front your arm must go through some range of motion before reaching 30 degrees, so why waste that part of the stroke even if it is only contributing a small amount to forward propulsion? I think this is where a "sprint" stroke versus a "distance" stroke diverge somewhat. In a sprint your goal is to apply as much force as you can. This means a rapid turnover and getting as much from your pull as possible. In distance you have to start emphasizing efficiency over pure power and that's where your vector mechanics come into play more.
I can see that it makes sense to mind efficiency a lot more for distance than for sprints. One aspect that makes looking at this far more complex is bio-mechanics. The structure and musculature that move the arm have optimum force, speed and efficiency production ranges and these might not exactly coincide with what is best for swimming...we did not evolve to be the best at moving through water.
