I've been skeptical about the alternative voting / instant run-off method that we'll be using in this next vote but this video a Gamefaqs user highlighted really explains the benefits of the system.

I'm convinced!
With this method the base splitting that would occur with people simultaneously going for Annie and Minette (as an example, not saying that the bases are necessarily analogous) is mitigated and a character that's more representative of the base's wants is chosen.
