How many days is it before you normally start an APB for a poster?

I don't want to start it too early cuz I think there should be no special rules for anyone on WTF (you know the way the Jordans, Bonds, Ramirez's of the world get special treatment), but I don't want to be late on it either. I don't want SDB thinking we don't care.

Any input by anyone on when the APB should be started?
