Look at the history of kata_web. A few games are rated for the bot (and not rated for the human opponent). Most of the time, the human’s rank is around 25k, but is in reality much stronger, low dan or high kyu. The bot can never rank up because the human opponents have a deflated rank, and the humans can never rank up because they only play bots and never humans, so we are locked in that situation. The only way out would be to make games ranked for the bot only if the human opponent has played enough games against humans.
