Yea, his comments concerning barrel movement (or not) in his discussion leaves a lot to be desired. He doubts barrel whip and the stretch theory.Hopefully some naysayer will agree that it's easier to prove cause and effect than the other way around. The effect is obvious and the cause is all that's left. Like proving 2+2 does NOT equal 4. Good luck to them with that, I guess but who knows with today's funny math. Like you said though...does it really matter to most? Most people can't scientifically describe how an internal combustion engine in a car works but they just hop in and go because they know it works.
