If I'm understanding the contention of the fellow who's dumping his OM gear,
he's confused by the positioning of the f/stop markings on the aperture
ring. They're an approximation at best on most lenses - at least in terms
of what one might expect of scientific instruments - but more than close
enough for a camera.
Using the camera's TTL metering won't prove or disprove anything -
especially with the OMs having auto-exposure when used in auto mode (which
is the best way to obtain the use of incremental apertures and/or shutter
speeds). It would have to be compared against exposures set based on
incident or separate spot metering.
Sounds like a non-issue to me.

Subject: [OM] The elusive f2: aperture scale inaccuracy?
...an OM defector...was dumping his OM gear in favor of another system.
He said, "Yeah, that Zuiko glass is nice - all those fast primes are great.
But you know, it disappoints me that none of them are actually f2 at
their widest aperture. Look closely at the aperture scale and you'll see
that the end of the scale is marked with a white line which *precedes*
f2...
