Not at all clear that that is proper resolution:
Looking at A/B, A/C, and B/C, each pair has ties.
Looking closer, no one hates C - perhaps reason enough to elect C,
since A and B each inspire dislike/hate.
Not ready for such detailed analysis, I like the 33% odds, and do not need
RVH to implement them.
