It is necessary to find a solution that is not only possible but also feasible
with little effort by ICC . If there are 1000 players online at ICC there are
usually about 30 computers if you don't count the house accounts so they are
more like guests.

The house accounts are btw the reason your otherwise good idea probably wouldn't
work well . They are dumbed down programs only playing humans and there are
plenty of them  ( the Bachs , the Wimps ... ) . So the average rating of (C)
accounts is probably much lower than that of the ones that allow any kind of
opponent .

There is no easy solution to the general problem .

One easy thing could be done by ICC though that probably would already help much
. At about 700 points rating difference there is a point where if the weaker
player loses he loses 0 rating points while the stronger player will lose 16
points when he draws and 32 when he loses .

This is one major reason for the formulas and the inflated ratings IMHO .

In this situation no player should be able to win or lose something . My
suggestion : when the rating difference is more than 700 points no rating
changes should take place and the games should be treated like they were unrated
. While not adressing the problem directly I expect this to be helpful .
