1 Very good! I really like the change to standard deviation, how ladder rating is calculated, map votes, that uneven custom games are excluded and afkers specced. 1 Very good!

3 The following two things make me curious, though:[q]Ratings now have higher variance, meaning they will allow for bigger changes between days.[/q]How much higher? What is the new [url=https://zero-k.info/Forum/Thread/25943]rating variability[/url] w²? Previously, it was already 35/day where only 14/day is used in the [url=https://www.remi-coulom.fr/WHR/WHR.pdf]WHR paper[/url]. If it is this ω² shown at the rating charts, I'm wondering in which units it is. Looking at current ZK ratings, it seems like variance has increased by a factor of about 2000. I see not a sinlge player, not even @Firepluk, with a standard deviation of less than 100. This means that all variances are now bigger than 10000. 3 The following two things make me curious, though:[q]Ratings now have higher variance, meaning they will allow for bigger changes between days.[/q]How much higher?

5 [q]Ratings will change faster the more games are played. [/q]What does this mean? 5 [q]Ratings will change faster the more games are played. [/q]Could you explain in more detail what this means?
