There are two problems with the KGS rankings:

One, they are weighed down a lot by past games from weaker versions.

Two, you have to worry about people trying to game the system. I found 
strong evidence that one of the frequent CrazyStone players was losing 
games intentionally against a weaker bot, while at the same time winning 
frequently against CrazyStone.

I brought this up with an admin, and he said they were looking into it, 
but several days have gone by and the player was not deranked (which is 
the usual punishment for gaming the system, and would remove past games 
from the rank calculation).
