ELO tells you "how player A performs compared to a given pool of players". There's no up or low limit, it's just a comparison. For example, in my private tests, I always set Averno 0.32 rating to zero, because I'm interested in know the advance in my newer versions compared to that. So, in my list, Crafty is 600-700 ELO. ICC is _a different pool_ and so ratings are not comparable in absolute terms. But they are in relative terms. For example, if Averno 0.32 and Crafty play on ICC, Crafty will have a lot more ELO than Averno. Let's say 3300 for Crafty and 2500 for Averno. José C.
