Chris--

You said:

Take this often-discussed example:
49: A
24: B
27: C>B

MMPO scores:  A52,  B49, C49.

The result is a tie between B and C.

I reply:

Yes, I was saying that when there are a few factions, each one voting exactly uniformly, as is necessarily the case in our examples, then MMPO can be indecisive. But what I also said is that, in a public election with thousands of voters, it's not going to be like that, and that indecisiveness won't happen.

You continue:

Which "one vote" would you change
(and how) to change this result into not a tie?

I reply:

I wouldn't change people's ballots. If I were in a committee in which that ballot-configuration occurred, I'd agree that it's a tie, rather than changing anyone's ballot. I personally don't have a problem with that tie. Maybe I'd suggest (in advance, of course) the use of Random Ballot for solving ties. If people insisted on using another rank-count to solve ties, I'd argue against any rank-count tiebreaker that would result in the loss of FBC compliance.

If it were a public election, then that wouldn't happen anyway. As I said, for obvious practical reasons, when writing examples, we specify a few factions, each of which votes perfectliy uniformly. Even the slightest deviiation from that uniformity would prevent that tie.
