Hi Don and all participants to that study, that is very interesting! The memory constrains are certainly a valid hypothesis, especially the default settings of the release are rather conservative on that side, because it seemed better to have a weaker player than begin to make the player's machine swapping... Those settings are rather fitting your memory constrains as well, so it is fine. Reading your email and looking at the curve, I wonder if one possible explanation could be an artifact on how the ratings are computed? My question is: what curve would we see for that study if the involved players were exactly linearly scalable? That seems silly, but I wondered if there were an underestimating of higher levels, because of the way the bayeselo works. I am also looking at the curve after the 5-6th level (~gnugo), as behavior may be different for very low levels. I don't know if my hypothesis makes sense. Sylvain
