I guess, if someone takes the SSDF or similar comp-comp ratings as the real rating interchangeable with human play ratings, one then expects a 2600 SSDF program to convincingly beat 2450 player pool (70% points). In fact, if one were to continue playing against the same human team, week after week, even if Rebel's book gets updated and engine parameters adjusted between the matches, its performance rating would keep dropping (not necessarily uniformly, but as a moving average over a longer sequence). And if the fixed Rebel were to play such sequence, the performance rating would drop much faster. As to which level it would eventually stabilize at -- it would be the rating just a bit above the strength of the weakest aspect of the program (probably would settle somewhere between 2200 and 2300 on a 400-500 Mhz Pentium, due to lack of planning beyond its 12-15 plies). Blitz, of course, is a different ball game. (But so is the postal chess, in which none of the micro programs would come out above the 2200.)
