Projected to December: 9% down · 91% stay · 0% up, from a year-end estimate of 3.61. Higher than today’s 3.59 because players this far below their band have historically finished nearer the middle of it.

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

By our estimated rating, not the published level.

Nicole 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.

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.
