Yeeesh. You had it on, dog, up until that. And don't try to tell me
(again) that I'm lying that you said it.

(Remember when you wrote this? "If reflected energy makes its way back
into the final amp, it was never generated in the first place, by
definition." Hint: apply the same idea to your "rearward-traveling
momentum" and you'll have it.)
