HOW RATINGS WORK

1. 1

   Ratings use WRPSA's versioned Elo v2 method: starting rating 1200, K=32, whole-number updates, and a floor of zero. Standard eligible matches have weight 1; king-of-court has weight 0.5. Both accounts are locked during the calculation, and the result, profile changes, rewards, and the match record are saved together.

2. 2

   The public order is rating, then the number of active rated results, then username (ignoring capitals), then account ID. Fewer than 30 active rated results is labelled provisional; no eligible rated result within 90 days is labelled inactive. These labels show how much someone has played and how recently. Elo v2 does not calculate rating deviation or a confidence interval, so WRPSA does not present them as statistical uncertainty.

3. 3

   Win rate is wins divided by active rated results. A correction removes the replaced result from this view and adds the reviewed result only after the rating reversal and the new rating update both check out.

4. 4

   The prediction check appears once at least 50 active Elo v2 rated results exist. There are 0 so far.

5. 5

   The full versioned method is available as machine-readable rating methodology and calibration data.
