I will try and get a photo showing the RES coming onto the beds, ahead of the BG. Oftentimes there will be only RES on the nests, while the male BG can be seen staging off in deeper water, waiting to come in.

"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.
