Notes

Carey - KGS just fixed a math error in their rating algorithm and it made a lot of people increase in rank instantly, sometimes as much as 6 ranks. Does any know if that affects this chart?

Malweth - This almost definitely affects this chart. It was perhaps a good move by KGS to strengthen their ranks... My guess is that this chart will take around 6 months to adjust (as things on KGS settle down).


[102] (Sebastian:) If this is really true, what about the correspondences in between 4D and 7D European - to which Japanese ranks do they correspond? Would it be possible to extend the table so that professional ranks are included? I heard, on IGS there is quite an overlap, and I seem to remember that 1p=5d there.


Fwiffo: With the recent ranking system changes at KGS, this chart is no longer accurate. One barometer for comparison would be GNU Go based robots. Most were about 9k (close to 8k) before recent changes, now most are 11k. Allegedly GNU Go is about 12k on IGS. At the higher end fo the spectrum, most dans seem to have lost about a stone (e.g. TheCaptain dropped from 5d to 4d).
