I don't think there's really anything more "implicit" about it. And you
could use the mean of a and b if you wanted it a bit less "implicit".  But
your other point is well taken, if you DO have a clearly defined "correct"
value, then that is the one to scale the error on. And it's a good idea to
provide that for those cases.

Care to help me write the PEP ?
