Naw, this just doesn't work. You just can't compare numbers from one tester
to numbers from another. There's too much potential for variation in the
testing methodologies, different standards, different skills on the part of
the tester.

You also can't compare MFT charts from different sources, for the same
reasons. The ONLY way you can compare any kind of data of this sort is if it
is done in the same lab to the same standards using the same methods and the
same equipment by the same tester. Otherwise it's meaningless. (Or worse,
misleading.)
