On April 4th, 2021, the EGD changed the rating algorithm.
You can read more about it on goratings.eu.
We will update / rewrite the EGD documentation accordingly soon!
In the meantime the old ratings are still available here.
Any questions just send us an email firstname.lastname@example.org.
The rating floor has moved from 20 kyu to 30 kyu. Please tell players
with the old 20 kyu floor to correct their rank. We will soon implement a Downward Rating Reset so these players also get the correct rating.
Ranks from the past won't be changed as it is technically kind of impossible to do this in hindsight.
