I prefer to add the KBr to the working developer solution.

With regard to the metabisulfite, I have mixed Pyrocat both ways, and with the films I am using have seen no differences in developer activity or stain levels (blue channel densitometry). I agree that it is more conservative to leave it in the formula.
Once again, my typing fingers were out of sync with my brain. One ml of Pyrocat stock A should contain .002 gram KBr, so 1 liter of stock should contain 2 grams.

One liter of working developer containing 10ml of stock A needs .02 grams of KBr, thus 1ml of a 2% stock solution of KBr.

Sorry!
