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.

Hello,
I'm new to the list. I'm a San Francisco resident and a software engineer, and I've recently gotten interesting in election methods. I have performed some alternative tallies of our ranked-choice ballots from last week:

I'm a bit mystified by the problems they ran into trying to do the instant run-off, since a full pairwise tally only took a few seconds on my old laptop. Of course the software and hardware designs are proprietary so we can't review them to understand what happened and how they fixed it...
