So I'm a little confused by the election results numbers coming out of San Francisco right now. The first-choice results on sfelections.sfgov.org/novemb… don't match the short RCV tables at sfelections.sfgov.org/novemb… and neither matches my calculations at dbaron.org/sf-elections-rcv/ . 1/2

The errors are pretty small -- but I'd have expected these things to match. I suppose the least bad explanation is that the reports were produced at slightly different times during a count that was adding ballots to the dataset. We'll see if the later results match... 2/2

OK, I figured out why my numbers didn't match the city's RCV results; I needed to discard marks that had the IsAmbiguous field set to true. So at least my RCV tables match the city's tables now.
