I think it depends somewhat on who cals it, and under what conditions
are stated.

I think if something is specified with an uncertainty of 10%, and is
found to be 9.9% off, then I feel it should be adjusted as it is close
to the limits of being acceptable, even though it is within spec.

Certainly with Agilent, you will pay more for the cal if you want both
"before" and "after" data.
