This is not responsive to the point I was making. Suppose crafty
clones A, B and C play with everyone and have rating 2700. According to you
they would have rating 2900-3000 if they just played humans. This means that
when A, B and C do play humans they will be picking up lots of rating points (as
their rating tries to move from 2700 to 2900-3000). For their rating to stay at
2700 they must be losing the rating points they are picking up from humans to
some of the computers they are also playing. Suppose they are losing points to
computers X, Y and Z. Then X, Y and Z must also be losing the rating points
they are winning from A, B and C back to the human pool (else the rating of X, Y
and Z would rise to the point that X, Y and Z stopped winning rating points from
A, B and C).
So the question I am asking is what are names of programs X, Y and Z
whose ratings would shoot up if they noplayed humans? If A, B and C actually
exist then conservation of rating points means X, Y and Z must exist also. As a
human I want to play X,Y and Z and grab some of those rating points.

Maybe crafty got a lot better and has driven the competition from the
field of battle.
