Projected to December: 14% down · 86% stay · 0% up, from a year-end estimate of 4.09. Higher than today’s 4.06 because players this far below their band have historically finished nearer the middle of it.

A 4.5 runs from 4.01 to 4.50. This rating sits in the bottom 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.

John 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

John has been 4.5 for all 7 seasons on record, but moved a long way inside it — from the bottom of the band to the middle.

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. The smaller, faded points — 2019, 2022 — rest on fewer than 5 matches, where the estimate is mostly the level the player was entered at rather than anything they did on court. Read the shape, not the value.

How you rank at your level
At 4.5, John has gone from the 71st to the 67th percentile of players at that level, 2023 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.

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.
