How your level works

The level

Your level goes from 0.0 to 7.0 and is shown with one decimal — 3.4, for example. It moves with every match that counts: up when you beat players who were stronger than you, down when you lose to players who were weaker.

level = (rating − 1000) / 140

Under the level there is a rating — the number the maths is done with. The level is that rating on a scale that is easy to read. “M”, “F” and “MX” are tournament categories, not a person's level.

Where you start

Before your first match, your level starts from what is known about you, in this order:

1. what a club coach certified in an Academy level test;
2. what you answered to “How do you play?”;
3. the level you gave when you entered a tournament (M4, F3, MX2…);
4. none of these: 3.2 when you play your first match (0.7 in a beginners' category).

Someone who has not answered, has not been certified and has not played a match that counts has no level — nobody is given a level they neither stated nor earned.

What counts

• Matches of the club's tournaments, with a result: weight 1.
• Open games and bookings with a confirmed result: weight 0.5 — they move half of what a tournament match does.

Not counted: walkovers, byes, cancelled matches, team ties (the players change from rubber to rubber), matches with no result, and tournaments not yet published.

Results outside tournaments

1. One of the players reports the result in the app or the portal — who played with whom and the sets — up to 14 days after the game.
2. The players on the other side are told. The result counts when one of them confirms it, or by itself after 24 hours if nobody disputes it.
3. If someone who played says it is wrong, the result is frozen and the club decides whether it counts.

Each person can report up to 4 results per day of play. A result entered by the club's staff counts at once.

How a match moves the level

1. Matches count in the order they were played. A side's strength is the average of its players.
2. The expected result (E) comes from the difference between the two sides: 400 rating points apart is about 10 to 1.
3. The actual result (S) is 80% win or loss (a draw: half) and 20% the margin — the share of the games (or points) you won, averaged per set. A 6-0 6-0 is worth 1; a win in the super tie-break, about 0.9.
4. Each player goes up or down by K × weight × (S − E). K is each player's own: 40 for the first 10 matches, 28 up to 30, 20 after. So two partners can move by different amounts in the same match.
5. The weight is the match's: 1 in a tournament, 0.5 in an open game or a booking.

E = 1 / (1 + 10^((R_B − R_A) / 400))
S = 0.8 × result + 0.2 × margin
R′ = R + K × weight × (S − E)

Provisional

For your first 10 matches the level is provisional: it is still finding you, so each match moves it more (K = 40).

If you stop playing

The level never drops because you are not playing. But after 182 days without a match that counts it is provisional again: your next 10 matches move it more, so the level finds you again quickly.

Verified by a coach

When you pass an Academy level test, the coach certifies that level — Academy level 4 is level 4.0 — and your profile shows the badge with their name and the date. If you had no match that counted yet, you are put exactly at that level; if your level was below it, it rises to it; if your results had already put you above, it stays where it is. From then on it moves with results, like everyone's.

In open games

An open game can have a level range (3.0–4.0, say). If you are inside it, you join; if you are outside — or have no level yet — you ask to join and the host accepts or declines. In a game with no range, “compatible” means within 0.9 of a level of the average of the players already in.

Equivalence to FPP levels

Beside your level you see “≈ FPP n”, to compare with the federation's level. This is the correspondence ClubMotion uses:

• The table is ClubMotion's calibration, not an FPP number: the federation classifies by its own rules (points in official tournaments) and ClubMotion neither reads nor copies federation data.
• It is the same scale for men, women and mixed, and only uses this club's matches — it is indicative and is reviewed as more results come in.
• With fewer than 10 matches the level is provisional: it is still finding you.

Who sees what

• The points ranking is public, with the names of those who played tournaments — like any sport's classification.
• A player's page (history, partners and level) is public only for those who switched their public profile on in the member area — off by default.
• For someone who has not, the page shows the name and the season's points, and says the rest is private. For a guest with no account, only the name and the points.
• Your level is always visible to you, to the club's staff and, in open games, to the other members who play with you.
