I agree with both Bob and you here. Besides, I belive the "scale" (if we can use this term) is smaler in human world than in comp-comp world, meaning that a small difference between two versions of a program (or two different programs, of course) can appear over and over in games, translating into more and more rating points. So, I think what Sonja said is nearly truth. If you know that program A has a stable "human rating" of Ea, and program B has a stable comp-comp rating of Ea+400, the human rating of B wouldn't be bigger than Ea+200 (I use smaller numbers because ELO system is not good with very big differences).
