How the foosball rating works
Every match recorded on SottoAlTavolo updates two numbers: how good you are in attack, and how good you are in defense. That is where your group's leaderboard comes from. Here is how it works, without formulas scribbled on a napkin.
The profile as it looks in the app: a striker who lets too much through in goal. The rating says it without mincing words.
Attack and defense are two different jobs
At the table there are people who live for the shot from the three-bar, and people who save everything from the goal. Treating them as a single number is unfair to both. That is why every player has a separate attack rating and defense rating, updated according to the role you played in each individual match. The average of the two is the score you appear with in the leaderboard.
The scale: from 0.01 to 7.00
The scale is inspired by Playtomic's, so if you play padel it will feel familiar:
When you sign up, a short self-assessment questionnaire sets your starting point. From then on, only matches count.
What moves the rating
After every competitive match the system compares the result with what it expected, given the strengths on the table. Three matches, three very different effects:
- The score really counts. Winning 10-3 and winning 10-9 are not the same victory, and the maths knows it.
- Opponents carry weight. Beating a stronger pair is worth a lot; thrashing beginners moves very little.
- It goes down as well as up. If you lose matches you were supposed to win, the rating records it. That is what makes the leaderboard credible.
Tournament matches count too: every match in the bracket enters the history as a real match.
Reliability: how "true" your rating is
Next to the rating there is a reliability indicator: it says how sure the system is about the number you see. With few matches reliability is low and the rating moves fast, because the system is still getting to know you. The more you play, the more it settles. A 4.20 with high reliability is worth more than a 4.80 built on three lucky matches.
Your group's leaderboard
The rating is personal, the leaderboard belongs to the place where you play: every venue has its own standings, built on the matches the group recorded there. No abstract rankings against strangers: the position that counts is the one among the people you actually play with.
Frequently asked questions
- What rating do you start from?
- It depends on the initial self-assessment: a beginner usually starts between 1.00 and 2.00, someone who has played for years higher up. Then the table corrects everything.
- Can the rating go down?
- Yes. That is the difference between a real leaderboard and an attendance list.
- Do friendly matches count?
- You can record friendly matches too, to keep track of them, but it is competitive mode that moves the rating.
- How much does it cost?
- Nothing: recording matches, ratings and the leaderboard are free.
Your group already plays. All that is missing is the leaderboard.
