Dear Kevin!

I thought the example you gave was the sincere preferences. If not, what
were the sincere preferences in that example and which was the sincere
CW in that example?

Still, SFC only refers to situations where "nobody reverses a
preference", so SFC doesn't help when people insincerely order-reverse.
I'd rather have pretty good strategy-proofness against order-reversal,
which DMC provides better than wv-Condorcet as Forest showed, than
complete strategy-proofness against half-hearted strategies where the
strategizers don't order-reverse for some unknown reason...

Yours, Jobst
