How Rankings Work
Ratings come from USA Roundnet's model. They update once, after each sanctioned event, based on who you beat and who you lost to.
Status
By rank| Status | Open | Women’s | Kept |
|---|---|---|---|
| Pro | 1–40 | 1–15 | 12 mo |
| Gold | 41–120 | 16–30 | 9 mo |
| Silver | 121–300 | 31–60 | 6 mo |
| Bronze | 301–600 | 61–120 | 3 mo |
Status can outlast your rank. Promotions apply monthly; drops apply each quarter (January, April, July, October) once the hold runs out.
Questions
What does the ± number mean?
That's the rating deviation (RD): how sure the model is about a rating. It starts wide for new players, tightens as they play, and grows again after about a month without an event. It never drops below 70 in Open or 60 in Women’s.
Why did my rating drop at an event I won?
Each game is scored against the model's pre-game odds. Heavy favorites gain little from a win and lose a lot from a loss, so a team can win an event and still go down. Open any event on a player page to see the odds and change game by game.
What counts?
Sanctioned USA Roundnet and Canadian events. Pool, bracket and consolation games all count the same, and scores and divisions don't change the math. Ratings update once after each event's results are uploaded.
Who shows up on the list?
Anyone with a sanctioned event in the last 365 days. Ratings are kept for 18 months in Open and 2 years in Women’s. After that, a player starts again as new.
Why am I on both lists?
Women also appear in Open. The two lists are separate, with separate ratings, so the numbers differ.
