what looks strange about oliebol is that he is in the first place but hasnt yet defeated the players which currently r in 2nd and 3rd, and he isnt even playing them at the moment

Ya I agree. That is a weakness in the algorithm. Once you get to the top it should be like king of the hill. You should keep having to play and beat other players at the top. And once you show that you can beat good players it should stop giving you bad players. Whats the point?
