Two estimates of the same thing, and why they don't always match to the decimal.
The short version
MatchMetric, TennisRecord and other rating sites all estimate the same thing: playing strength on the NTRP scale, from USTA league results. Neither is an official USTA rating, and the numbers won’t always match to the decimal. A difference of a few hundredths usually comes down to how each site weighs a match, and how recently it picked up your latest result.
How MatchMetric rates a match
The score and the margin. A 6–4, 6–4 win counts for more than a pair of tiebreaks.
Each doubles partner separately. Your partner’s rating matters, so two partners don’t get the same number from one match.
Every night. Once a result reaches TennisLink, it counts here that night, and you can see what each match did to your rating.
Confidence. A player with two matches doesn’t look as certain as one with twenty. Every rating shows how much evidence sits behind it.

MatchMetric also has captain tools: availability, lineups compared by win probability, and opponent scouting. TennisRecord is a separate site we don’t run.
How we check our numbers
Against USTA's year-end ratings. Across 4,940 NorCal players with 10+ matches in 2025, we compare where our rating put each player with whether USTA moved them up, down or not at all.
Against real results. Across 307,034 rated matches since 2025, we compare our pre-match win probability with who actually won. A player with a half-point rating edge wins 90% of the time.
In public, before USTA's release. We freeze our bump odds for every NorCal player before year-end ratings come out, then grade every call, misses included, on the accuracy page.
The charts for the first two are on the home page. We don’t claim to be more accurate than TennisRecord. These are the checks, and you can judge the results.
Common questions
Why is my MatchMetric rating different from my TennisRecord rating?
Both sites estimate your strength on the NTRP scale from league results, but each weighs a match its own way. MatchMetric uses the score and the margin, rates each doubles partner separately, and updates every night. A result that reaches TennisLink counts here that night, so if one site has your latest match and the other doesn't yet, that alone can explain the gap.
Which one is right?
Neither is your official rating. Both are estimates of the level USTA will publish. We publish how ours compares with USTA's year-end ratings and with real match results so you can judge it yourself.
Is either one an official USTA rating?
No. MatchMetric is not affiliated with, endorsed by, or operated by the USTA, and TennisRecord also says it isn't affiliated with USTA. For league eligibility and standings, your official USTA rating is what counts.
Does MatchMetric cover my section?
Only USTA NorCal for now, adult and mixed league play. Tournament results don't count toward these ratings. Other sections can ask for coverage from the section menu.
