Fascinating, but *why* is it so? I remember reading an explanation for the 'unbendable arm' that explained the strength. Apparently the primary muscles change with extension, allowing those on the surface to absorb tension and bend easier. Mightn't this aspect come into this category too?
Why is it so and how is it used in conjunction with the correct basic skills.... that might be a more complete question. The question is just one of several examples I thought of to illustrate my discussion with Rob Liberti yesterday in re: "a person often doesn't know what he doesn't know".
