There's no such transfer in plurality voting (where you only vote for
one option). That transfer happens in instant-runoff voting, but I
didn't compare our condorcet results with IRV results. That's not easy
to do accurately because you can't rank several options at the same
level with IRV, so you would have to ignore a lot of ballots.
