Why level matters more than price
A player who loses 6-0 three weeks running or wins without breaking sweat stops booking, and no discount brings them back. Rating players and grouping them by level is the one thing a club can do that a public court cannot. It is also what turns a booking site into a place people come to find a game.
Ratings also change what the desk can sell. A player with a known level can be offered a session, a box, or a partner, rather than a bare court. That offer is the difference between a club and a court rental.
02
Choose a scale the desk can explain in one sentence
Use a scale from 1.0 to 7.0 in half steps, or a plain 1 to 7. Anything with more precision than a half step invites arguments over decimals that nobody can measure. The desk should be able to say what a 3.5 looks like in one sentence: rallies of 6 or more shots, serves in, knows the rules, loses to a 4.5 most weeks.
Write a one-line description for each step and put it on the sign-up page. Players will place themselves against it more honestly than most clubs expect, as long as the descriptions are about what they can do and not about how good they are.
- Half steps from 1.0 to 7.0, no finer
- One line per step describing what the player can do
- The same scale for every sport at the club, with sport-specific descriptions
03
Give the first rating in three parts
A new player self-rates at sign-up against the descriptions. The coach or the host of their first open play session confirms or adjusts it within 1 step. The rating then floats for the first 3 recorded matches, moving by a full step if results say so, and settles after that.
The floating period is what stops the first rating from being a fight. The player knows the number will correct itself, and the coach does not have to argue on the spot. Mark floating players on the roster so hosts can seat them with care.
04
Let results move the rating in small steps
After the floating period, a match moves each player’s rating by a small fraction of a step, more when the result was unexpected and less when the favourite won as expected. A 3.5 who beats a 4.5 moves up further than a 3.5 who beats a 3.0. Margin matters a little, the opponent’s rating matters more.
Only matches with both players confirming the score should count. Practice sets, coach lessons, and open play rounds where partners rotated every 20 minutes should not, or the rating fills with noise. League and ladder matches are the reliable input.
- Small steps after settling, larger when the result was a surprise
- Only results confirmed by both players count
- League and ladder matches in, practice and rotated open play out
05
Use bands, not exact numbers, for grouping
Open play sessions, box leagues, and class levels group by band, not by rating. A band is a range, for example 3.0 to 4.0, wide enough that a session can fill and narrow enough that the matches are close. Three or 4 bands per sport is enough for most clubs. Show the band on every session and league page so a player knows before booking whether they belong.
Bands should overlap slightly at the edges, so a 4.0 can book the 3.0 to 4.0 session and the 4.0 to 5.0 session. Players at a boundary get a choice, and the club fills 2 sessions instead of arguing about which one the player belongs in.
06
Handle disputes with the rule, not the desk
A player who thinks their rating is wrong asks for a review, plays 3 league or ladder matches, and the results decide. The desk never changes a rating by hand for a settled player. Publishing this rule ends most disputes before they start, because the only way to prove a rating wrong is to win.
The one exception is a rating that was clearly entered wrong, such as a 6.5 given to a beginner by a typo. Fix those on the same day, note the correction in the player’s record, and move on.
