I think you're confusing with practicality with legality. OVC represents an
overcast which represents a ceiling. 001 OVC is 100' ceiling which is less
than any of the published minimums. 1/8 SM represents a visibility and on
the ground that is less than RVR 2400 or any of the other published
minimums.

We were speaking legall; I think we agree that legally the 001OVC
1/8SM is not significant. In my experience with fog it isn't
necessarily significant from a practical point of view either
because...
1) Fog is rarely uniform. 1/8 at the end of the runway may be 1/2 mile
at the other end. That is why RVR is often quoted in "touch down" and
"roll out", sometimes even 3 locations.
2) At 200 feet you may be in the clouds but its common to be able to
pick the rabbit out from the clouds. The rabbit is very high intensity
and commonly pierces through the clouds (which is its purpose).
Sometimes I'll fly 1/2 a dot off to the right so the rabbit appears
below me out the window.
