How Rankings Work

How they're calculated and what they show

Ever wonder how player rankings are calculated each week? Here’s a quick breakdown of how we track progress and performance throughout the season.

Initial Rankings

At the start of the season, each player receives a baseline rating based on their WTN (World Tennis Number) using the formula:

(40 - WTN) × 100

Players without an existing WTN were assigned a number based on their Placement Combine performance. In some cases, adjustments may be made after a visual assessment to ensure fair placement for everyone.

Earning Match Points

Each week, players gain or lose points depending on their match outcomes. The calculation takes into account several key factors:

Base Points: +100 for a win, -50 for a loss

Opponent Strength: Wins against higher-ranked players earn more points

Match Recency: Matches played in the last 35 days are weighted up to 1.3x

Match Type: Doubles matches count for 80% of singles match value

Point Limits

To keep competition balanced and fair:

Every win awards at least +50 points

Every loss deducts no more than -50 points

These limits help prevent extreme swings in rankings while still rewarding strong performance.

Weekly Ranking Updates

Rankings are updated at the end of each week once all matches are completed. Your new ranking = last week’s ranking + (points earned or lost this week). The point changes next to the player rankings will show the total point increases or decreases from the start of the season.

This rolling system highlights consistent effort and improvement across the season, so every match truly counts! 💪🎾
