From the docs people helpfully linked: http://www.glicko.net/glicko/glicko2.pdf
The Glicko-2 system works best when the number of games in a rating period is moderate to large, say an average of at least 10-15 games per player in a rating period. The length of time for a rating period is at the discretion of the administrator.
Following on my previous post, I was hoping that someone could say what the ratings period for OGS is. (Strangely, details of the Glicko math used were entirely absent, despite the fact everyone knew the buzzword.)
Your score updates each game, but a ratings period of a single game is a major violation of the Glicko math.
So I’m wondering:
- How are we updating scores each game?
- What is the Glicko ratings period?
