Harvey,
Your explanation is as good as any I've read elsewhere. I
think I still have a Frank Berto article in which he explains
all this stuff. If I'm lucky, I be able to find it in my giant
pile of cycling stuff. And if I do, I'll scan it and post
it... somewhere.
But my recollection is that articles on this subject are not
much more informative than your message. Just longer 9and with
pictures).
Cheers,
