Guild Wars 2

I need the exact rating formula used to calculate ratings based on WvW score

It’s called Glicko 2.

You can find it here: http://www.glicko.net/glicko/glicko2.pdf

Thx Marty but…

I already knew it was the Glicko 2 system. But I heard they modified it a bit to make it works for their rankings. Do you know what changes they made?

Thx again but the information in that blog post is too vague…

Here are a subset of the things I would need :

- How does Anet use the Glicko 2 system with 2 opponents instead of only 1
- How does Anet calculate the value of “Sm” in the Glicko 2 system
- How many matchs are played between each rating calculation (this one I expect 1…)
- What value is the system constant “T”
- etc…

I know it’s a lot but if anyone has this info I would greatly appreciate to have it. I know some people do because they can calculate the ratings on their website. Here are 2 examples :
