Robert is one of 856 men at 4.0 in this cohort of 3225. Levels at or below 4.0 account for 86% of them. Shown for men only: NTRP is a gender-specific standard, so a pooled curve would compare against the wrong bar.

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

Robert has played at 3.5, 4.0 across 5 seasons — 1 move up and 0 down.

3.03.54.020192021202220232025

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 3.5, Robert has gone from the 78th to the 88th percentile of players at that level, 2019 to 2021.

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.
