Re: [Paddlewise] paddle analysis expectations

Michael,
Your comment below is exactly the reason for my relentless nagging 
about the need to obtain "measurements" that will reveal true 
answers.

Not only can we not accurately "feel" small differences, I think we 
also can not distinguish between real differences in efficiency and 
differences due to the relative strengths of varied sets of muscles 
brought into play by different paddles and strokes.

Tests on humans have shown that they cannot accurately perceive
differences of less than,  ummm, can't remember exactly, but it's
something on the order of 10%.
