What a dGrade is here
A player's dGrade is their dynamic grade from the world rankings — the running rating that moves game by game. This tool doesn't compute it; it pulls it, and uses it for exactly two things: seeding (blocks, doubles pairing, knockout draws, auto-assignment between competitions) and display (the roster, and the public page if you show dGrades).
Refreshing
↻ Refresh dGrades in the event header re-pulls current ratings for the whole roster; the header pill shows when they were last taken. Completed events can't refresh — their dGrades are the record of what the seeding actually used. American Six Wicket events have no ratings to pull, so the button isn't shown; seeding uses the estimated grades entered on the roster.
When a refresh finishes, a line under the header reports what it did, for example ✓ dGrades refreshed at 14:05 — 80 players checked, 12 dGrades changed, 2 without a dGrade. WCF rankings as of 30 Sep, 13:50. The count is of pairs in a doubles event, and of entries in an event that mixes singles and doubles. see which opens the list of changed dGrades with each player's old and new figure. A refresh in which no rating moved reads no dGrades changed. The rankings time is when the WCF (or, for AC events, the AC rankings) last published the figures the refresh read.
Two consequences of a refresh worth knowing:
- If the new ratings change the rank order, seeded blocks are flagged as stale — nothing re-seeds by itself.
- If you've announced "seedings are as of <date>", set the dGrade cutoff date — after it, Refresh asks before silently re-taking ratings.
Refresh reads this site's copy of the world rankings, which is updated from the WCF every six hours. Between updates, a grade the WCF has just published isn't in it yet.
Get latest WCF grades
Accounts with the WCF Championship permission see Get latest WCF grades beside Refresh dGrades. It fetches the rankings from the WCF straight away instead of waiting for the six-hourly update, then runs Refresh dGrades for this event. The fetch usually starts within two minutes and takes about five, and the page can be used meanwhile. A line under the button shows where it is:
- Waiting for sync… — Step 1 of 3 · Requested at 14:02 (3 min ago): the request is queued for the grade sync.
- Syncing with WCF… — Step 2 of 3 · Sync started at 14:04 (1 min ago): the rankings are being fetched and imported.
- The fetch has finished — ✓ WCF grades published 30 Sep, 13:50 are in: the sync finished at 14:09 and imported rankings for 5,120 players — and Refresh dGrades runs for this event, with its result line under the header.
The request is remembered in the browser it was made from. Closing or reloading the page doesn't cancel it: reopening the event in the same browser picks up the progress line again, and if the fetch finished while the page was closed, the event's refresh runs then. If the WCF hasn't published since the last update, the line says Already up to date and nothing changes. A request with no answer after 20 minutes is reported as not having reported back; reopening the page later checks it again.
The World Championship uses this between the block stage and the knockout: once the WCF publishes grades that include the block games, the knockout is seeded on them (see Block Separation by Grade).
Players without a rating
Entrants added manually get an estimated dGrade — your judgment, used only for seeding inside this event. A player left without one can't be auto-balanced into blocks or doubles pairs; even a rough estimate lets seeding place them. Refine the estimate any time from the roster.
Current vs max-12-months
Seeding can use each player's current dGrade or their highest in the last 12 months — a per-competition choice on Format. The two differ only for players whose grade has dropped in the last year: max-12-months seeds them on the higher, earlier figure; current seeds them on the grade today.
