The system at a glance
Every module is one piece of the rating. Read them in order or jump to the one you're after.
Updated · 27 July 2026The rating in 60 seconds
The essentialsOne number from 1.0 to 10.0. Three layers: your division (the whole number), your rung (the decimal) and a progress bar toward the next rung. Above them, four SERIES group the divisions, from the highest to the lowest.
- Wins add points. Losses never subtract them.
- Only your best wins count: farming rivals four rungs below adds nothing at all.
- The decimal isn't a percentage: it's a rung you validated.
- Changing division takes the points AND a key win.
- Friendlies and doubles don't touch the rating.
- Your confirmed division is a floor: the rating never drops below it.
What it is
A number from 1.0 to 10.0 that says your real tennis level. It's earned on court: official systems only set your starting point.
From BORN to LEGEND. That's how we move.
The top rung of every division (the .5 or the .7) is the door to the next one. A 2.7 is someone standing at the door of 3.
Above the divisions there are four SERIES, the first being the highest and the fourth the lowest. Every SERIES groups whole divisions, so no player is ever split between two.
The rungs and their thresholds aren't invented: they copy the official ladder of the French Tennis Federation, decades of calibration behind them, beginner rungs added in July 2025 included. B4T makes it global.
How you start
You have an official ranking: pick the system, type your rating, and you enter at the rung it points to. Your federation already validated it for you, there's nothing to prove.
The tables below say exactly where you land.
You choose honestly. You also enter confirmed: there's nothing to validate.
No trials, no waiting. From there it's all earned on court.
The 10 is never seeded, it's earned. Your confirmed division is a floor the rating never breaks through. The rungs inside it are recalculated every month from your last 12 months: your division is your identity, your rung is your recent form.

Which matches count
Competitive. The only one that moves the rating.
Stays in your stats and history.
Don't count toward the rating.
It counts as it was on match day. And losses never subtract points.
The engine, in detail
For those who want to understand the system in depth. You don't need this to play.
The engine
Recalculated every month
Every month the engine takes your B4T matches from the last 12 months and checks whether you clear the threshold: the one of your current rung to hold it, the next one's to climb. Because results expire after 12 months, just like on the pro tour.
There's nothing to wait for: it counts from your very first match. The 12 months are a window that moves with you, not a trial period and not an anniversary you have to reach.
Adds up your best wins. Only a limited number of them.
Compares that total against the rung's threshold.
To change division, the points aren't enough on their own.
It never starts from your current number, that would be circular. Your confirmed division only comes in at the end, as a floor: the entry rung it never lets you fall below.
BORN climbs on wins
No points, no thresholds
| Rung | What it takes |
|---|---|
| 1.0 | Entry, nothing to prove |
| 1.3 | 4 wins |
| 1.5 | 8 wins (wins by W.O. don't count) |
| 1.7 | 12 wins, or beating someone at rung 1.7 or above |
The first rungs ask for wins, not points: B4T matches from the last 12 months, counted.
Simple on purpose. Whoever is starting out shouldn't have to understand any threshold, just go and win matches. The points system starts at ROOKIE.
What a win is worth
The scale, from ROOKIE up
Aiming at 3.0: beating a 3.5 pays 90, a 3.0 pays 60, a 2.7 pays 30, a 2.3 pays 20. Four rungs below pays nothing at all. Your own number never enters the formula: two players aiming at 3.0 who beat the same rival get exactly the same.
One win against a 3.5, and what it pays depending on the rung you're aiming at.
The same win is worth less the higher you aim. That's why nobody climbs by farming easy rivals.
The threshold of every rung
Official table, by gender
| Rung | Threshold ♂ | Threshold ♀ | Wins ♂ | Wins ♀ |
|---|---|---|---|---|
| 2.0 | 6 | 6 | 6 | 6 |
| 2.3 | 70 | 70 | 6 | 6 |
| 2.7 | 120 | 120 | 6 | 6 |
| 3.0 | 170 | 170 | 6 | 6 |
| 3.5 | 210 | 210 | 6 | 6 |
| 4.0 | 285 | 265 | 8 | 8 |
| 4.5 | 305 | 295 | 8 | 8 |
| 5.0 | 315 | 305 | 8 | 8 |
| 5.5 | 325 | 305 | 8 | 8 |
| 6.0 | 335 | 325 | 8 | 8 |
| 6.3 | 360 | 345 | 8 | 8 |
| 6.7 | 420 | 385 | 9 | 9 |
| 7.0 | 435 | 395 | 9 | 9 |
| 7.3 | 435 | 430 | 9 | 9 |
| 7.7 | 475 | 500 | 10 | 10 |
| 8.0 | 505 | 560 | 10 | 11 |
| 8.3 | 550 | 610 | 11 | 12 |
| 8.7 | 610 | 630 | 12 | 14 |
| 9.0 | 765 | 760 | 15 | 15 |
| 9.3 | 865 | 740 | 17 | 16 |
| 9.7 | 930 | 780 | 19 | 17 |
7.0 and 7.3 ask men for the same 435, and it isn't a mistake. The higher you aim, the less those same rivals are worth, so putting 435 together at 7.3 is harder than at 7.0. The threshold is the same, the distance isn't.
Same story with the women's 9.3 (740, lower than the 9.0). Wins devalued by distance, plus a bigger quota of counted wins. What it really takes goes up.
Which column applies follows the player's gender, not any play preference they set.
The engine weighs your wins and losses against the rung you're aiming at, not against your own. Positive balance, it counts you 1 extra win; comfortably positive, 2. Negative, you keep the wins of your quota.
What each result weighs on that balance: these are balance points, not rating points.
Losing to someone far below the rung you're chasing is the clearest sign that you aren't of that rung yet, and that's why it weighs the most.
None of this touches your points. A loss never takes points away, it just doesn't add any: the worst a negative balance does is leave you without the extra counted win. Playing upward never punishes you.
Your profile always shows how many points you're carrying toward the next rung.
The number doesn't move until you validate. The bar does, every month.
The division key
Points aren't enough
Inside your division you climb rungs as you earn points and clear each rung's threshold. To change division you need two things: reaching that division's threshold (its entry rung, the X.0) and one of these two, in the last 12 months.
One win against someone from the division you're aiming at, or above.
The points prove you're regular. This win proves you can handle the people up there.
Two wins against different rivals from the top rung of your own division.
Two of them, and against different rivals, on purpose: beating the same player twice doesn't say what beating the two best in your division says.
You stay at the top rung of your division with the bar full: the points are already there, the win that opens the division is missing.
Everyone starts at 1 and 2. The best climb the inside rungs on their own up to the top, 2.7. Whoever beats two different 2.7s opens their division 3, and from then on a single win against that 3 is enough for everyone else. That 3 climbs to 3.5, whoever beats them opens the 4.
Rung by rung, always on court.
LEGEND
Not reached by points or fast track
Whoever arrives gets a global number by order of arrival. One single worldwide list: your flag already says your country. It's the app's roll of honour.
Protections
Your confirmed division is a floor: the rating never goes below its entry rung.
Stop defending your points and your wins age out of the 12 months: the rung comes back down. It's recalculated every month, with no anniversary to wait for. You're still a RISER: what moved is your form, not your identity.
Only then does the division itself give way: a 3.5 with a full year without B4T matches drops to division 2. Never more than one per year.
Winning again puts you back where you belong.
A real season
Marco, 11 B4T matchesA RISER ten points short of moving the number.
The key of the 3 came from those two wins against 3.5: they belong to division 3, so they are Way 1. Without them the points would be there and the division would not.
The losses only cost him the balance bonus.
And this isn't a lab example: the numbers come from a real season played by a licensed player, and the B4T engine landed on the same verdict as their federation.
Everyone is born at BORN. The summit is called LEGEND.
And in between, just matches.
