Guild Wars 2

The evolution numbers are as following:
Arborstone +69.145
Far Shiverpeaks -67.547
Gandara +15.772

I don’t know if thats an error on the millenium site or if im mistaken about the whole ELO system, but shouldnt it add up to 0?

The system just added 17.37 points into the ranking.
All the other matchups add up to 0.

You can calculate it yourself using the formula’s anet provided. Glicko isn’t ELO.

It is correct. Glicko calculations do not always balance out at 0.

It wouldn’t surprise me if there are errors, due to the strangeness with the EU matchups this past week. but things should be correct from this week forward.

But to answer your question, GW2 uses the Glicko-2 system, not ELO. in ELO rating changes all add up to zero, but in Glicko-2 it’s possible for them to add up to non-zero amounts, due to the influence of deviation and volatility.
