Right, I hadn't thought through all consequences of all examples being
from self-play. That's indeed the only way to get inconsistencies in
that scenario. I'm fairly certain that the situation is quite
different in games against other players though, especially stronger
ones. Losses in handicap games (with GNU Go as black) is likely to be
a good class of game records to investigate.
