Yeah, drifting is in my opinion, one of the best parts of the forum. You go in expecting one result, and the conversation takes an unexpected turn and before you know it you're learning and discussing something new. Trying to direct the course of a thread on PB is like herding cats... you make a suggestion and a course correction here and there, but the final destination is still somewhat of a mystery. And it's good.
"Forget pounds and ounces, I'm figuring displacement!"
If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
