Oddly enough most all tubes check at about the same percentage. The meter movement is not jammed disallowing further deflection. I am going to try to find the url for, or cut and paste the paragraph I found describing this very condition.
There are a few really nice pages or sites on tube testers in general. The ins' and, well; no outs concerning the nearly lost understanding of transconductance and the measurement of micromhos'. There are dynamic conductance testers out there that are mistaken and thus often misrepresented for sale as a true mutual conductance tester. Supposedly Hickok held the rights to the "real deal" for a long time and other manufacturers were forced to come up with gimmicks.
