Many vintage testers have specifications for what a given tube type should measure to be considered ‘good’ or ‘bad’. These specifications were developed when tube manufacture was closely controlled, even across manufacturers, and therefore a given tube type could be expected to show similar if slightly varying measurements. RCA, Sylvania, Phillips, Tungsol, etc all used the same spec for building a given tube.
That is not the case today, as we have widely varying measurements within a given type. This is due to lack of specifications about what a certain tube type should be. The Maxi-Matcher does not offer pass/fail standards for tubes, but functions more appropriately as a comparison test bed for tubes in your stock or available from your manufacturers.
