Why do you think James Green-Armytage was talking about unbounded ballots?

I still think your disagreement is silly, primarily because I don't understand
how "giving everyone one vote" shows that we implicitly measure interpersonal
utility.

And even if I did understand that, I still think it's silly, since just because
we "implicitly do" measure interpersonal utility doesn't mean we really *can*
measure it, which would require that all voters are sincere and use exactly
the same rating scale. Ballots would have to read minds.

And how did you get here? Why would anyone advocate the cumulative vote for 
a single-winner election?

IRNR is your method, so I would think it would be obvious to you that the
normalization is rubbish without the eliminations.
