Every time you register a match result, your play level is updated immediately.
The better you play, the higher your level. Most players have 4 stars or less.
Top-tier club players have 7 stars, world top players have 10 stars.
Fast and accurate
Achieving an accurate estimate typically requires just three match results. This is made possible through the utilization of advanced mathematical models.
Expected score
Your level increases if your score is better than expected, even if you lose the match (and vice versa). For example: You have 2 stars and you lose by a small margin to a player 3 stars. In that case, your playing level will go up and the playing level of your opponent will go down.
New players
Your level does not change when you play against a new player, unless you are a new player yourself.
Level corrections
Occasionally, your level may change, even if you don't play a match:
- A player of your league plays against a player of another league. The results of the match may be used to adjust the average of all league players.
- The national average level has changed. For example: When many new players join, the average level decreases. All player ratings are adjusted to ensure that the national average level remains the same.
For geeks
The play level of an individual player is influenced by a myriad of biological factors such as fitness, strength, reaction speed and intelligence. Each of these factors follows a normal distribution, much like the height of a person. The product of many normally distributed factors forms a lognormal distribution.
We have developed advanced models to quickly estimate play levels based on match results. Play levels are transformed to a normal distribution with a mean of 0. The normalized play level is mapped to stars by regularly calculating the standard deviation, allowing us to calculate the Z-factor for each player. A Z-factor of 0 corresponds to a 4-star rating, while a Z-factor of 0.75 earns a 5-star rating, and a Z-factor of 1.5 equates to a 6-star rating.
This approach ensures that only about 1% of the player population achieves 7 or more stars, signifying top-tier club players, and a mere 3 in a million reach the pinnacle with 10 or more stars, representing world-class players.
