I think that for the same reason people should not count the game that Rebel lost against Shredder and I find it unfair that part of the chess players in Israel read that Rebel lost against Shredder without getting the information about the reason so maybe counting the last game as a win is justice because shredder enjoyed from something that it did not deserve to enjoy. If you count the last game as a win for shredder then the performance of shredder is 2630.6 if you count only the games against players with rating above 2230.6(shredder won the other games). The performance of Fritz6 based on the Israeli league is 2393.8888 Uri
