In Response To: Who is the better BG player: the one who has the lowest error rate, or the one who somehow maximizes the difference between his errror rate and that of his opponent? (happyjuggler0)

It doesn't look like anyone has tried to address your question as stated in the subject line (although I felt compelled to change the subject line since such a long subject line hurts my eyes), as opposed to the question that I think you intended to ask.

I have in the past pondered whether the relative error rate is a good measure of what you're asking about. The trouble with using error rate to gauge a person's ability to adapt to the opponent is that the error rates are still measured against (the bot's estimate of) perfect play. If, when you and I play, your moves are weak vs. perfect, but my moves are weaker vs. perfect, does that mean your moves are good versus me? Seems plausible at first glance but I don't think it follows logically. Suppose your ER when training against a bot is typically about 3, whereas mine is 7. Suppose further that when you and I play head-to-head, your ER is typically 4 and mine is 12. Are you doing better against me than a bot would? Are you even necessarily doing better against me than you would if you played your normal 3 and I played my normal 7? Maybe I'm the one who knows how to take a big risk against you to elicit an uncharacteristic error that gives me a great chance to win the match. In these sorts of atypical situations I don't believe one can automatically take a difference in ER and translate that into MWC.
