The Slams rating is the playing level that Slams tracks automatically for every player. It is Slams' own rating, on the same scale as the Dutch KNLTB; it is not the official KNLTB rating. After each qualifying match, Slams calculates a new rating, so you always have an up-to-date and fair picture of the level in your club. As an admin you don't have to do anything for it: enter the result and the rating updates itself.
The scale: 1.0000 to 10.9999
The rating runs from 1.0000 to 10.9999. Important to know: a lower number means a stronger player. Your playing level follows from the rating: a rating of 8.5 belongs to playing level 8, and from 8.999 it is playing level 9, the beginner level. A new player without official matches starts at 8.999. The rating is tracked to four decimal places (for example 7.8420), so even small differences stay visible.
What winning and losing do
Win a match and your rating goes down, which is actually progress. Lose and it goes up. How far you move depends on the strength of the opponent:
- Beat a stronger team and your rating moves more.
- Beat a weaker team and the move is small.
- Lose to a weaker team and your level drops faster.
Each match only makes a small adjustment, so a single result won't turn your rating upside down. The team rating is the average of the two players. After the match, each player gets a new rating individually. On the player profile you'll see the rating with a graph of the progress, where an improvement runs upward in the graph.
