In http://www.aishdas.org/asp/2009/04/halakhah-and-phenomenology-4.shtml
I discuss a similar sugya on Qiddushin 64.

You are referring to a different entity, even though both are called
"chazaqah". Yes, a chazaqah demei'iqarah is weaker than a rov, but
a chazaqah disvara is a presumption based on a logical causal chain.
Ein adam chotei velo lo -- a person with no motivation to sin wouldn't
choose to sin. (Assuming he knows it's assur.) But this causality is
only valid because it actually usually happens that way, barring other
factors. Every chazaqah disvara must also be backed by a ruba deleisa
leqaman, or else it would indicate that our sevara was wrong.

At least, that's how I understand Sheiv Shemaatsa 6:22.

But then, whenever a chazaqah demei'iqrah is against a rov, it also has
to be a chazaqah de'ika rei'usa. The rei'usa being another wording of
the same idea is having an "against".

But my attempted point was simpler...

When I mentioned umdena, I meant: If tav lemeisiv is a statement about
social standing that didn't apply to a matrionis, and matrionae were
easily identifiable, why does tav lemeisiv apply to them too?

And when I mentioned rov, I meant: In many cases it's efshar levareir,
so how can you rely upon the chazaqah / rov / any of the rules of
birur? It is at most a majority that you can prove this matrionis does
not belong to.
