If I understand correctly, then only methods that actually do candidate
elimination (and fail LIIA) make use of exclusion counts. Minmax (the
Condorcet method) doesn't. For that matter, plain old FPTP/Plurality
doesn't either: the winner is the candidate with the most first
preferences, and there are no eliminations as part of the process.

Did I get that right?
