So, how do you gain firing pin travel and simultaneously shorten the ramp (cocking distance) w/o having a rebounding firing pin? Earlier you stated that consistent ignition is paramount, and it is. Your measured data puts your actions at 70 oz-in, which is right on par w what my spring choice is.

It's not calculus in this case; it's algebra. I do not believe Otteson's data is erroneous. He clearly states the assumptions and conditions he uses to arrive at his conclusions. To call out a published and well accepted book is quite a bold move.
