I don't see it having to add up. The +ROI players are getting less because there is less to get. They are closer to perfection and you can't get better than that. The -ROI players might get more. On the other hand, if someone could be bad enough to lose all the time, they might still lose all the time and the chips would be worthless to them as well.

It doesn't have to add up because we are talking about different situations, like one game with 1 good player and 9 average players and a separate game with 1 bad player and 9 average players.
