Black won 37 games, White won 42 games, and there was 1 jigo.

Players

Three players registered for the Formal division and none for the Open division. I used gnugo3pt8 to make an even number and avoid byes.

Results

AyaMC won all 40 of its games, an impressive record, and as far as I know, an all-time world record for a single tournament.

There was only one jigo, a surprisingly low number for eighty 9×9 games. Even allowing that AyaMC was significantly stronger than the other three players, there were forty games among the other three players, so I would expect more than one jigo.
