Your padel level changes automatically after each confirmed match score. Nettla looks at the result, how close it was, and the levels of your partner and opponents. Feedback from the other players has a small extra effect.
Match results
Winning moves your level up and losing moves it down.
Beating stronger opponents counts for more, and close matches count for less than clear wins.
Your partner's level matters too.
Lower levels, and players with fewer matches, move faster.
Peer feedback
After reporting a score, each player can rate the others' level as As expected, Higher or Lower.
Feedback is anonymous: "Other players do not see your feedback".
It only counts if a player gets at least 2 votes, and it only has a small effect.
Give it soon after the match. Feedback given after the level update has run isn't used.
Reliability
Your level card shows a reliability percentage. It reflects how accurate your level is likely to be, based on how many matches you've played and how recently. It goes up as you play more.
When levels don't change
Tennis matches, and sports without levels.
Matches marked as not played, or unfinished matches with no completed set.
Scores that are disputed and not resolved by the club.
League matches in a round where the club has turned off level changes.
Good to know
If you don't play a padel match for 90 days, your level drops by 0.10. It drops again every 90 days you stay inactive, and never goes below 1.00.
Your level updates about an hour after the score is confirmed. See "When will my level update after a match?".
