Odds are that you won't need to hit a PD within a few tenths anyway. As far as the wires needing to be within 20 millionths....how many of us can even verify a measurement to that tolerance? That is probably the acceptable limit when thread wires are used to verify thread gages in a controlled environment, but average use would not demand it.
Right, on closer examination the quote from MH references thread gages.
I will probably never even use my set of wires, but I really want it to be complete!
