Yeah, you can just rank them by standard deviation.

Bump.

I've been thinking about why some graphs have linear corelation, and why "Points Distribution" look so weird.
So, I concluded that after more games, the point difference between two players tends to grow - which would mean one of them is getting better (his win % chance grow), and the other is getting worse, is that correct? Or does it mean they are simply ranked more precisely? What I'm saying is, shouldn't the scores stabilize after some time?

For 1vs1 ladder, max score and min score don't differ that much compared to the past, while definitely we have more games now (in the same time interval). Why? Is this because the games expire, and number of games per player is similar to what is used to be?

How would scores for 1vs1 ladder look without game expiration? Or at least with more months? Can someone check that for me pretty please?
