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.

The following two things make me curious, though:

*quote:* Ratings now have higher variance, meaning they will allow for bigger changes between days. |

How much higher? What is the new

rating variability w²? Previously, it was already 35/day where only 14/day is used in the

WHR paper. 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.

*quote:* Ratings will change faster the more games are played. |

Could you explain in more detail what this means?
