I think, in short, that the "situation" (of odds distribution)
is not relevant to FBC. I think the quoted definition answers
the question this way: In neither situation 1 nor situation 2 (which
I assume to be obtained by voting differently) could the voter
obtain a "result" preferable to the best result in the other
situation.

I have to interpret "result" to mean "the candidate who actually
got the seat," since as you have noticed, a ranking of candidates can't 
usually be used to rank probability distributions.

Pretending Mike agrees with my interpretation (and that he clarifies FBC 
accordingly), do you think FBC would then be unambiguous?
