## What is MatchMetric?

Know where you actually stand.

MatchMetric turns published USTA NorCal league results into a performance rating that updates every night — not once a month. Your rating moves after every match, and you can see exactly which match moved it.

FOR PLAYERS

• A live rating with a confidence band — not just your published level • Your full match log, each rating shown as it stood at match time • Bump watch: how far you are from the next level, up or down • Head-to-head against anyone you've played, or anyone you're about to • A match predictor: your win probability against any opponent, not a hunch • Nightly movers across the section — who's climbing, who's cooling off • Season Wrapped: signature wins, peak rating, longest streak

FOR CAPTAINS — Co-Captain

• Shared availability. One In / Maybe / Out sheet per match, no group-chat roll call • Lineups: every lineup ranked by the chance of winning the team match, using singles and doubles ratings, the real flight format, and proven partnerships • Opponent scouting: what the other team usually fields, plus their strongest and most stacked looks • Practice planner: balanced, partner-fresh pairings, and partner chemistry that builds over the season

HOW THE RATING WORKS

Every match you play produces a performance rating, measured against who you played and how the sets went. Those roll into a rating with a confidence band that widens when we've seen less of you. It recalibrates nightly against published NTRP levels.

Ratings are ESTIMATED. USTA's NTRP algorithm is proprietary and this is not it, and MatchMetric is not affiliated with or endorsed by the USTA. Ratings here never change your official level.

COVERAGE

USTA NorCal leagues — Adult, Mixed, Combo, Tri-Level and postseason. Free during the beta.
