In terms of learning something about go, this exercise was not worth much. However, I do think the methodology can help to pinpoint positions that a bot is likely to be misevaluating, to what degree, and in whose favor, even though we cannot say what is best play.

I think it also bolsters my rule of thumb, already stated, that with Leela Elf 100K we should not worry about possible errors of less than 3%. OC, this is only one game, one bot, and one setting. More research on other games, other bots, and other settings could well be of value. But the main takeaway, IMHO, is this:
Don't sweat the small stuff.
