Projected to December: 0% down · 99% stay · 1% up, from a year-end estimate of 2.82. Lower than today’s 2.87 because form regresses — players this far into their band partway through a season have historically finished nearer the middle of it. Keep playing at this level and the numbers above are the ones that hold.

A 3.0 runs from 2.51 to 3.00. This rating sits in the upper half of the band, and every match moves it.

Christa 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

Christa has been 3.0 for all 8 seasons on record, but moved a long way inside it — from the middle of the band to the top.

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, Christa has gone from the 18th to the 8th percentile of players at that level, 2019 to 2025.

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.
