Emma is ranked against players at the same level in the same place. The published level is identical for everyone in a band, so it cannot separate them — our estimate can. Groups smaller than five are not ranked at all, because a placing out of two is noise dressed as standing.
Over timerating by season, and how you rank
Rating by season

Emma has been a steady 4.5 across all 3 seasons on record.

4.04.5201920222026

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 — 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, Emma has gone from the 19th to the 4th percentile of players at that level, 2019 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.
