Why not go along with it for a month (have done so a few weeks now) rather than have an excuse to be adversaries.
See, now with that, you're screwing yourself over doubly! You're going along but still arguing with him over it. So that means you get none of the credit for doing it his way AND what he'll remember is you trying to browbeat him into being wrong. (that's how he'll see it--not that you actually browbeat him, but you know how we all get when we feel criticized.)
