The earlier observations seem to suggest that the Goko ranking is fairly reasonable (that is, close to the trueskill leaderboard) near the top of the ranking. Has anyone looked at how they compare for the lower ranks? Or is it too hard to retrieve a full Goko ranking?
I'm asking because I noticed by chance that the bots seem to rank higher in the Trueskill list.
Bottington has now level 14 in Trueskill and rating 3576 in Goko (and three other bots are, btw, between levels 12-13 so their levels are quite stable). I checked three human players who also have level 14 in Trueskill (and enough games, at least 500 for each) and each of those had rating around 4500 in Goko, full 1000 points higher. The same holds for ranks; Bottington is ranked 886 in Trueskill and around 1500 in Goko, whereas the humans were around 900 in Trueskill and around 700 in Goko. The opposite check shows similar signs. Three arbitrary managers ranked near Bottington in Goko had levels 4, 8 and 11 in Isotropic. These are again lower than Bottington's rank in Trueskill.
Overall, it looks like the bots have at least some hundreds of points too low rating in Goko or, equivalently, perhaps 5-10 levels too high rating in Trueskill. If we believe Trueskill to be a better estimate, then this implies that pushing one's rating up in Goko by beating the bots is actually a bit harder than it should be. In fact, this also matches my own experience. I've played primarily against bots (because I very often need to pause during playing) and my rank in Trueskill is 156 compared to 673 in Goko.
Disclaimer: The above observation might simply be because of very small and potentially biased sample.
