Thanks for 1. As for 2, it's not the outcome that would be horrible, so much as that the counting method impacts who wins. And in fairness to me, I'm just coming up with hypos off the top of my head, which is why I chose easy round numbers and close vote totals.
That said, I think you're right that this would probably only matter in very close elections. And very close elections have a certain arbitrariness to them anyway. I'd have to think more to know if it's more generally a problem outside of niche scenarios. I doubt it.
I think total vote would solve this particular problem, though again I would want to think it through before committing (or at least do a bit of algebra), and I'm not going to do that now. It doesn't really matter all that much. If RCV passed in every state, even if my concerns are valid, they just wouldn't be significant compared to some of our other vote counting methods or election laws generally. So I'm not opposed to it. I'm just not enthused about it. If I had to decide whether to vote for it, I'd give it more careful consideration. Probably I would.
