Hi Chris,
Good to hear from you! Some replies follow...
>I agree with your positive remarks about Raynaud here. I regard
>Raynaud(Gross Loser) as one of the easy-to-explain contenders.
I agree that Raynaud is easy to explain. I don't know about Gross Loser,
though... Winning votes is most intuitive to me. "This candidate was
opposed by 60% of voters in a pairwise contest! Eliminate him! Bam!"
I guess the GL equivalent would be "This candidate only got 30% of the
vote in a pairwise contest! Eliminate him! Bam!" I dunno... maybe.

I think that I understand your definitions. Can you prove that
Raynaud(GL) meets this criterion?

Personally, I don't care a lot about random fill incentive... but are you
sure that it doesn't exist in this method? It seems like it would generate
some sort of queer incentive, but I don't know exactly what kind yet.

Hang on a moment... when did we establish that Raynaud was far less
vulnerable to burying than defeat dropping methods?? I mean, if it is,
that's great, but I don't remember anyone demonstrating that...
my best,
James
