We all know KGS, you may like it, you may dislike it. But we must all agree in how crazy his rating is.
Last September, KGS decided to modify its internal rating. Now, it is supposed to be more difficult to reach high levels while the lower levels are narrower; so lots of players concentrate at the 15k-1k zone. Everyone was affected by this change and players’ rating grew about 5 stones by this procedure. Everyone was affected in the same way, so all your opponents also increased by 5 stones their level.
It is well-known that internet ratings are slightly higher than the real ones: as you can see KGS’ ratings are always a few stones higher than AGA’s or European’s on the lowest levels which should be restored somewhere later to have a good equivalence on the higher ratings.
Where is that?
It’s on the 9k. As you can see, a 9k KGS player varies up to 4 stones on each real scale.

So, if KGS has to recovers this 4 stones at the 9k level… why didn’t they leave the old system? Sincerely, I don’t know the answer. I don’t mean that KGS2 rating is better than KGS3, but it may have been more "real".
Talking about "better"… I think that none of the KGS rating systems are good. For example: how can you improve your level at KGS? By NOT playing.
In fact, my original account at KGS "alejo" showed this image today:
Which is something obviously wrong. I haven’t played with this name for a couple of months and there are only 3 games listed for the last 6 months… As you can see, inactivity is the best way to increase your rating.
The real fact is that I’m at 9k. Yes, 9k at KGS, which means that I don’t know where I’m at all.
