The specs on the tag were measured before the bow was adjusted for your draw length. It's very common that the ata changes a bit when they time after a draw length change unless the tech is really anal about resetting to specs.

Correcting the brace and ata will relieve some of the tension on your bow, so you'll actually reduce your draw weight by doing so.

I ultimately have to ask, "why?" What are you trying to gain by resetting the bh and ata? Poundage I get, but the other? Who cares?
