It is perfectly plausible that (on rare occasion) you may get a under
performing lens in a manufactured series. It might be that it just squeaks

absolutely. that's why a scientific lens test would require a large
random sample. there also is the phenomenon of cherry picking lenses,
and you can just as easily get an overachieving one that is better than the
typical instance too. Generally olympus lenses have good quality control and
fairly even performance though. one of the reasons Pop Photo and other
photo rag tests are not reliable is that the lens manufacturer supplies
the sample to be tested, so they can supply a cherry-picked instance.
Part of what makes 3rd party lenses cheaper is less rigorous quality control,
so they can have more variance in quality, but when the manufacturer
supplies a single instance to Pop Photo to be tested, they can supply
a top performing sample.
