About MasterLeague

Origins

MasterLeague has been operating and evolving since 2021. The original concept proved so successful during initial trials that its core structure has not changed since then.

Rotating-Partner Doubles Format

Players are organised into courts with 4–6 participants of comparable ability. The format accommodates groups up to seven players if there is only one court. Fixtures run approximately three hours, allowing for two rounds.

After the first round, the top and bottom player on each court (by total points won) are promoted or relegated to the next court above or below, if there is one, for the second and usually final round during that fixture. Remaining players are reranked but stay on their current court.

Although it sounds simple, there are many factors taken into consideration. The minutiae of MasterLeague's format and rules accommodate everything from handling late arrivals or injuries to synchronising the end of the first round and calculating player ladder points across different courts with different numbers of players.

More Than a Rating System

While DUPR provides ability ratings, MasterLeague delivers competitive experiences that rating systems alone cannot. Experiences such as overtaking a superior player are seen as a flaw within a rating system, but are an integral feature of a competition.

Features celebrated include in-round rankings, ladder position, winning streaks, win/loss differentials, and improvement rates — as well as prizes.

Unified Ladders

As the format spread to multiple clubs, a unified ladder system became necessary to fairly compare results from different groups playing at different times and places. MasterLeague brings players' results together into unified ladders, calculating ladder points that are comparable even between players who have never played together.

Court Allocation

Player court placement starts with DUPR ratings rather than ladder points. The top 4–6 players are placed on court 1, the second group on court 2, and so on.

New participants provide a self-assessed skill level for court allocation in their first fixture, but this does not influence ladder points.

Points Formula

The MasterLeague points formula considers:

• Player ratings — Higher-rated courts yield more potential ladder points.
• Best round performance — Personal best round serves as the baseline, protecting occasional participants.
• Win/loss record — Stronger track records advance players up the ladder.
• AWOL penalties — Applied for missed events without withdrawing. Penalties diminish logarithmically over time as attendance increases.

Current YTD and QTD player points are based on each player's personal best round in the period and net win/loss differential to date, less any AWOL deduction.

Points Potential by Skill Rating

The formula yields varying potential points depending on the average skill rating of the court. Playing on a higher-rated court gives everyone on it more earning potential.

Overlapping Points Potential

Court placement does not limit earning potential. A player who wins every game on a court will earn about the same MasterLeague points as a player who wins two thirds as many points on a court with an average skill rating 0.5 higher. Similarly, a player who wins three out of four games will earn about the same as a player who wins half their games on a court rated 0.5 higher.

Proper initial court placement still matters for rule consistency and to maximise earning potential — the higher the average player rating on a court, the more points everyone on that court can earn for the same number of game points won.

Club Ladder Points

Club points are based on the proportion of MasterLeague rotating-doubles ladder points won by players from each club, using the MasterLeague formula at the index 5.0 player skill rating. This means club points are not dependent on the skill level of the players.
