Alexi: By my rough estimate, by the time you reach 13kyu, you are still in the bottom 10% of confident accounts. 5kyu is the median. 25 and 75% are at 9kyu and 2kyu.


There was a major upwards shift in the ranks in September 2006.

Number of active users vs rank (comparison between March 2005 and May 2006)

And this is for users with confident rank

The number of active accounts at confident rank 30k was not available in March 2005 data, so it is impossible to compare how much it has changed since last year. Meanwhile, the peak of the histogram has shifted from 12k to 13k, and a small peak at 16k shifted to 17k. The other peaks identified a year ago became less significant. Now there are more players with confident rank in the range from 29k up to 5k. However, the number of stronger players (4k up) has either decreased or remained the same. Nonetheless, there are more 9d players now than a year ago.

The number of players vs rank histogram for KGS

This graph is based on the data received from Bill Shubert on March 3rd, 2005.

Median: 12k


zinger: Surprisingly normal-looking, at least to me. I was expecting it to be much flatter betwen maybe 20k-5k, and also thicker on the weak side of the bulge than the strong side. Shows how much I know :)

Calvin: Perhaps you're more used to seeing tournament data. See the AGA Rating Histogram and the DGS Rating Histogram pages very different distributions.

nachtrabe: I hope nobody minds, but I've taken the liberty of cleaning up the graph a bit. You can still see the original: [ext] http://xs18.xs.to/pics/05096/kgs.png

KGS rank histogram based on the players who have confident rank (see data).
There are several local peaks: at 11-12k, 8-9k, 6k, and 2k. There is also a small peak at 16k.

%[DrStraw] - Here is another interesting graph. The three lines %represent the number of accounts of each rank in total, those %accessed in the last 3 months, and those accessed in the last %month. I was surprised at the remarkable similarity of each %graph. I expect that the accounts which have not been accessed %more recently would have shown a much stronger mean value.
