ELO ranking

ELO estimates a player's strength relative to everyone else in the club. Beating a stronger opponent earns more points than beating a weaker one, and the loser loses exactly what the winner gains — every match balances to zero.

• Everyone starts at 1000 points.
• After a match the winner gains as many points as the loser gives up — at most 32.
• The bigger the favourite's lead, the less a win gives them, and the more the weaker player gets for winning.

Every match played in a tournament or league counts, including one ended by a retirement. A walkover does not change the ranking. A result corrected by the club recalculates the ranking from scratch.

ELO is tracked per player, but a pair's strength in a doubles match is the arithmetic mean of both partners' ratings. All four players gain or lose the same number of points.

Every player starts at 1000 points on each ladder. Ladders are separate in each club category: for men, women and mixed, for singles and doubles, and for each discipline. The rating updates when a match result is entered — and that date is the one used for the time windows and in match history. Walkovers never affect ELO — retirements (a player withdrawing mid-match) do.

Streak badge (e.g. 3 W)

Shows the player's current run: green means consecutive wins, red consecutive losses. It appears from three identical results in a row, and the counter stops at 10 — a longer run still shows 10. A walkover neither extends nor breaks the run.

Rating line

The small chart next to the rating traces ELO over the most recent matches — each point is the rating after one match, at most 15 points. It is drawn only from three matches played, because a shorter line says nothing.

The three bars

• Wins — The win percentage across the player's whole history on this ladder, with the number of matches played in parentheses.
• Last 60 days — The win percentage in the last 60 days, plus the signed ELO point balance gained or lost in that window.
• Tiebreaks — The share of tiebreaks won. This bar only appears once the player has played a first tiebreak.

Bar colors

Blue at 100%, green from 67%, yellow from 34% to 66.9%, red below 34%.

Small sample

With fewer than 5 matches in the 60-day window, the bar itself is pulled towards the player's overall win rate — the printed percentage stays raw. That way a single match can't read as career-best form.

The ranking list only shows players who have played at least one match in the last 365 days.
