I'm surprised the complete ballots were available in a form that would
allow pairwise tallies.
From the Chronicle article I saw, it looked as though _none_ of the
four races requiring a second round ended up with the eventual winner
recieving a majority of votes. Did this turn out to be the case?
If so, I wonder if SF removed the "majority" requirment from their city
charter when IRV was implemented. Could be messy otherwise.
