Bill I worry about the HSB ability to keep recruitment of native BG under control...especially where a feeding program is implemented.

Now HBG.....that's another story, and the direction I was going to suggest he consider. wink (once the particulars are known)

"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.
