If Eric has a surface plate and an indicator you could check them.

Going back to tolerance stacks, have you measured the runout of your wheels on the surface that you are aligning from?
I just looked up the tolerance specs for aluminum wheels, and the ranges given are surprisingly large. No wonder BMW wants people to align off the hubs using their special heads.
