Steve wrote a stronger, but more complicated clone (or near-clone)
criterion, but I must admit that the criteria that I understand are
the ones that are defined in one paragraph. If I understood that
criterion, and it were shown that Schulze meets it and Tideman(wv)
doesn't, then I don't deny that that would likely count for Schulze
against Tideman(wv).
If there's a briefly-defined clone criterion, and it's demonstrated
that Schulze meets it and Tideman(wv) doesn't meet it, would you
re-state its definition here? Or tell me its message-number in the
archives?

I was interested more in the winner comparison between Tideman(wv)
& Schulze, because those methods were the contenders for best.
I've suggested SD & SSD for public proposals, but, because they
don't meet the clone criterion, and because their monotonicity is
more in doubt, I don't consider them as contenders for absolute best.
I must have missed it if someone said that they'd demonstrated that
SD & SSD lose to Schulze in winner comparisons. I'm not saying it
isn't true, only that I missed the statement. I'll check the
archives message you refer to above.

I know. I no longer use that claim.

I'll check it out.
