A 4.0 runs from 3.51 to 4.00. This rating sits in the upper half of the band, and every match moves it.

Our estimate, not a USTA figure — scale measured at this point of 2023 on 2160 players. Graded publicly in December when USTA publishes year-end ratings. It moves when you play, and occasionally when we improve the model.

Where you rank
ID · 4.0
42 of 123

Cory is ranked among players at the same level in the same place, by our estimated dynamic rating — not the published level, which is the same for everyone in the band. Groups smaller than five are not ranked, because a placing out of two is noise dressed as standing.

Over timerating by season, and how you rank
Rating by season

Cory has been 4.0 for all 8 seasons on record, but moved a long way inside it — from the bottom of the band to the top.

3.54.020192020202120222023202420252026

The line is our estimate; the horizontal lines are level boundaries, so crossing one is a bump. Hollow points are years we inferred from the level played the following season, because USTA publishes a current rating but no history.

How you rank at your level
At 4.0, Cory has gone from the 65th to the 49th percentile of players at that level, 2020 to 2026.

Percentile compares the same level in the same season, by share of games won. Mixed is shown for context — USTA rules exclude it from your adult rating unless mixed is all you play.

Games won matters more than matches won — NTRP adjusts on margins.

What an account addsprivate to you

Signing in lets you point an account at your own record and keep things alongside it: notes on individual matches, your racquet and string setup, restring reminders, friendly matches that never reach TennisLink, and a diary of what you changed and what happened after.

None of it is visible to anyone else. Not to other players, not on your public page, not in search. Every private table is scoped to your account at the database level, so it is enforced rather than promised. The public page you are looking at is built from USTA match results and nothing else.

Not affiliated with or endorsed by the USTA. Rating shown is the published USTA year-end figure; match data is from USTA TennisLink.
