How Ranking Works

Every player has a skill rating in each match sport of their club. You choose a starting tier once. After that, every match you play adjusts your rating automatically: you never have to change it yourself.

1

Choose your starting tier

When you join or create a club, you choose the tier that best matches your experience today:

100 points

Beginner

New to the sport, learning basic rules, serves and shot consistency.

200 points

Intermediate

Plays regularly, understands court positioning and strategy, and maintains consistent rallies.

300 points

Advanced

Highly competitive, strong shot accuracy, and tournament or structured league experience.

Don't worry about picking the perfect tier on Day 1. Your initial rating is just a starting line. As you play matches in your Club, your rating naturally adjusts based on your actual match results.

Not sure? Answer three quick questions and we'll suggest a tier. You can change your choice until your first rated match.

2

Each team's average

In doubles (2 vs 2), each team's rating is the average of its two players, using their ratings from before the match:

Team Average = (Player 1 Rating + Player 2 Rating) ÷ 2

Team A: 200 + 200

Average 200

Team B: 200 + 100

Average 150

3

The 20-point tolerance rule

We compare the two team averages to decide whether your opponents were higher, the same, or lower:

  • Same average: the difference is 20 points or less, for example 200 vs 215, or 200 vs 220.
  • Higher average: the opponents are more than 20 points higher, for example you 200, them 230.
  • Lower average: the opponents are more than 20 points lower, for example you 200, them 175.

Points earned or lost

OpponentWinLoss
Higher average+20 Underdog bonus−5 Protected loss
Same average+10 Standard win−10 Standard loss
Lower average+5 Expected win−20 Upset penalty

Both players on the winning team get the same points, and both players on the losing team lose the same points. Each player's own rating changes by that amount. Everything is worked out from the ratings before the match, and each match counts once.

Example

Team A (200 + 200, average 200) plays Team B (200 + 100, average 150). Team B wins. Team A's average was 50 points higher, so Team B beat a higher-average team (+20 each) and Team A lost to a lower-average team (−20 each).

PlayerBeforeChangeAfter
Player 1 (Team A)200−20180
Player 2 (Team A)200−20180
Player 3 (Team B)200+20220
Player 4 (Team B)100+20120

Your rating corrects itself

Started too high? Pick Advanced (300) but keep losing to lower-average teams, and you drop 20 each time: 300 → 280 → 260 → 240, until your matches become balanced.

Started too low? Pick Beginner (100) but keep beating higher-average teams, and you gain 20 each time: 100 → 120 → 140 → 160 → 180 → 200, up to Intermediate.

Nobody is locked into a tier. Your current rating always comes from your actual match history.

Your level and profile

Your level follows your current rating:

  • Beginner: below 200 points
  • Intermediate: 200 to 299 points
  • Advanced: 300 points and above

Your profile shows your current rating and level, the starting tier you chose, your rated matches, wins and losses, and how many points you've gained or lost since you started.

For every match you can see the result, your team's average, the opponents' average, whether they were Higher, Same or Lower, the points you earned or lost, and your rating before and after. For example: WIN · your team 150 vs 200 · Higher average · +20 · 100 → 120.

Questions

Do I have to answer the three questions?+
No. You must choose a starting tier, but the questions are optional: answer them if you're not sure, and we'll suggest a tier. You can still pick a different one.
Can I change my starting tier?+
Yes, until you play your first rated match in that sport. After that your matches decide. If your rating is clearly wrong, an organiser can set it from your profile, and it applies from then on.
Can my rating go below 100 or above 300?+
Yes. Ratings keep moving with your results, with no upper limit. The lowest possible rating is 0.
Is my level decided by the tier I picked or by my rating?+
By your current rating. Your starting tier stays on your profile as your original selection, but the level shown next to your rating follows your results.
Which sports and matches count?+
Every scored match in a match sport (such as badminton, pickleball, or a club's own match sport like tennis) played in your club. In singles, each side's "average" is simply that player's rating. Running, cycling and attendance-only activities don't have ratings.
I'm in two clubs. Do I have one rating?+
No, one per club. Your rating in one club only changes with matches in that club.
Does winning 21–3 count more than 22–20?+
No. Only who won matters, not the score or the number of sets.
A score was entered wrongly. What happens?+
Fix or delete the match, and every rating is recalculated from the start as if it had always been right. A match is never counted twice.
What does Provisional mean?+
Fewer than 5 rated matches. Provisional players are listed below the leaderboard until their rating has had time to settle.
Who can see my rating?+
Members of the same club. Your answers to the starting questions are never shown. See the Privacy Policy.
Do ratings change who I'm paired with?+
Yes. Random pairings use ratings to keep each match evenly balanced, while still mixing up partners.

The aim is simple: fairer, more competitive matches, without anyone managing their own rating. More about clubs, sessions and payments in the FAQ. Questions? Email info@arc12box.com.
