UTR Rating is a modified elo rating system that promotes fair and competitive play across the tennis world. Players are rated based on actual results, not age, gender, nationality, or socioeconomic status.

When you understand your skill level, you can find hits, events, and tournaments where you’ll have fun, play competitive tennis, and improve your game. All you need to know is your UTR Rating!

**Meet Taylor! **Our UTR Sports Rating Bot Betais powered by ChatGPT will engage with you around the UTR Rating. This is an early beta - we want to get tons of feedback from you and appreciate you taking the time. A few things to note:

- ChatGPT has limitations and sometimes does funny things called 'hallucinations' - this is a limitation of GPT and is well documented, but getting better
- Taylor is not directly connected to your individual profile but can answer questions if given context and examples

**What is a**** ****UTR Rating****? Why should I have one? **

UTR Rating is a number that provides a real and accurate measurement of skill level. A player’s UTR is a number between 1.00 and 16.50.

One match result is all it takes to receive a projected UTR Rating. After approximately five matches, the rating becomes fully reliable. As matches are played and entered into the system, a player’s UTR will increase or decrease over time as per the following methodology.

**How is it calculated? **

For each match, the algorithm calculates a match rating and a match weight for each player. A player’s UTR Rating is the weighted average of up to 30 of their most recent match ratings. Only matches within the last 12 months count toward a player’s UTR.

**Calculating Match Rating**

Two factors are considered when calculating the match rating. The first factor is the UTR Rating difference between opponents. The second factor is the competitiveness of the match, as determined by the percent of total games won.

Given the UTR Rating difference, the algorithm expects a certain percent of total games won. The player who performs better than the algorithm’s expectation will see their match rating go up while the other player’s match rating will go down. When one player’s match rating increases, the other player’s match rating decreases by the same amount.

Note: If the two players have a different number of matches counting toward their rating, the overall UTR Rating may not increase or decrease by the same amount.

**Calculating Match Weight**

The following factors are used in the match weight calculation:

*Format* – As the match format increases in length, more weight is given. A match with a three-set format receives more weight than a match with an eight-game pro set format.

*Competitiveness* – As the UTR Rating difference between players increases, less weight is given. For example, imagine a player with a UTR of 6.00. A match played against an opponent with a UTR Rating of 5.00 or 7.00 receives more weight than a match played against an opponent with a UTR of 4.00 or 8.00.

*Reliability *– As the reliability of the opponent’s UTR Rating increases, more weight is given. A match played against an opponent who competes often and thus has a reliable UTR Rating receives more weight.

*Time Degradation *– As prior matches get older, less weight is given. Since the algorithm is a representation of the current form, it gives more credit to matches played within the last few months.

**Ways to Improve Your ****UTR Rating**

Play Well – Performing well in matches is the easiest way to improve your UTR Rating. If the match is out of hand, don’t give up! It does not matter whether you play higher- or lower-rated opponents; you can improve your UTR either way by winning more games than expected.

Play Often – The more matches you play, the quicker your UTR Rating will reflect your current form. The algorithm is especially accurate for those who play often against a variety of opponents rated above and below you.

Be Patient – Since your UTR Rating is a rolling weighted average, the effect of new results is slightly lagged. Your UTR Rating may not fully reflect a recent outcome right away, but it will over time.
