No, I am speaking of ICC *standard* rating (typically 30 min each), not blitz rating, or bullet rating. Nobody has 3600 there. Standard ratings on ICC don't seem inflated. I'm not certain blitz ratings are either.
I played a match between ChessV and Zillions in Capablanca Chess long ago and it ended 2½-2½. But I think ChessV is better today.
Anyway, your rating evaluation builds on matches between computers, which won't work because Zillions can never accumulate rating by beating weaker opponents as there aren't any. So its rating can only go in one direction. Should it play against humans its rating would be decidedly higher than you estimate.
