Holy sacred cow, Batman!!

According to Brian's analysis, Miller was the Condorcet winner, but
Kiss won the actual IRV election.  Miller was preferred over Kiss 3991
to 3455.

Brian, the number of first-choice votes according to your histograms
doesn't exactly match the numbers on the Burlington election site, for
the first round summary.  For example, you show Kiss got 3808
first-choice votes, but the election site shows 3809.  Do you know
what caused the discrepancies?  Did you account for spoiled and
truncated ballots correctly?

Thanks for doing this analysis!  This is BIG news in the small world
of voting methods! :-)
