I have 3 altimeters as well....Advanced Flight EFIS, G5, and a standard round gauge. Last IFR cert, the round gauge didn't make the cut and was placarded for VFR only, but the airplane was still signed off for IFR.

With multiple altimeters this approach sure seems reasonable. I also have done this in the past, but don't know if it is consistent with the regulations given the 91.411 cited above.

In MacCool's example BOTH were checked, but one failed and was tagged. So they know not to rely on it.
OP's question sounded to me like, "do I have to check them all" I truly hope the answer is check them all, and tag two if you must, but know their status.
