DUPR Algo Updates 1/30: What You Need to Know

February 7, 2024

After months of research and gathering feedback from users, we are excited to announce that on January 30th, we will release key updates and improvements to the DUPR algorithm. We are confident these updates will create even more accuracy within our rating and a better experience for pickleball players everywhere.

Tomorrow, we're releasing a new blog post that provides a behind-the-scenes look at DUPR's research process and how it contributes to the continual advancement of the algorithm.

As of January 30th, DUPR takes into account:

  1. Points Matter. Was this a tight match or a blowout? DUPR now evaluates the closeness of the match, so a score of 11-0 will have a bigger impact on your rating than a close match of 11-9 against that same opponent
  2. Recency Matters. A match you played today will impact your rating more than a match you played six months ago.
  3. Total Match Count Matters. If you've played in a lot of matches, your rating will fluctuate less compared to a player with a lower match count.
  4. Every Match Matters (even against unrated players). Every match counts towards your rating, even if you are playing against someone who is unrated or new to DUPR.


So what does the updated rating mean for you? We’ve tried to answer the most common questions from our community below.

Do these changes start now or will they be applied to all my past matches?

These updates will be applied across all your match results in our platform on January 30th, as well as to all future results you submit. Want to ensure your rating is accurate and up to date? Hit the court and share your results.

Why is DUPR updating the algorithm again? Is this going to happen frequently?

Our team of data scientists is dedicated to ensuring DUPR is the world’s best and most accurate global pickleball rating. As we get more players and results onto the platform, and have more data at our disposal, we are able to make improvements and updates to the system to ensure that DUPR is providing the most accurate assessment of level. We’re confident that each of these updates will improve the foundational accuracy of the rating. On 1/26/2024, we're releasing a blog post that provides a behind-the-scenes look at DUPR's research process and how it contributes to the continual advancement  of the algorithm. Will be linked here.

When do matches start to matter less? Is there a certain number of matches that count more (ie my most recent 5 matches)? When do matches start losing their value?

The weight of each match decays with each day that passes by. That means that any match played on the same day will have the same weight before considering the number of sets in the match. The match weight decays smoothly, so there is no cutoff for when a match is no longer counting.

What if all the players involved are not rated?

If all players are unrated, we do not know the level of the match, so we take a guess that the level is 3.5. The outcome of the match will push one team above 3.5 and the other below to properly reflect the levels displayed by the scores of the match. With each player’s next few matches, they will be able to move quickly toward their appropriate level, especially once they are playing rated players around their skill level.

Can my rating go down if I win?

No! You will be awarded a rating increase for each win, but the amount depends on many factors including your win probability, all players’ reliability, the score, the result type, and more.

Will my rating change if I haven’t logged in matches for a long period of time? I have 200 games entered but haven’t played in a year. How does that affect my rating?

A pause in playing will not directly affect your rating, but rather your reliability. In order to keep a reliable rating, we recommend that you continue to participate in DUPR logged or reported matches on a regular basis. If you jump back in after a break, you can expect some fluctuations in your rating in your first few matches back since your rating reached a low level of reliability. Once you record more matches, your rating will start to stabilize again and more accurately represent your current skill level.

A Beginner's Guide to Pickleball

Pickleball has been gaining popularity rapidly in recent years, and for good reason. It's a fun, social, and accessible sport suitable for people of all ages and skill levels. If you're new to pickleball or considering giving it a try, this beginner's guide will walk you through everything you need to know to get started, including pickleball ratings. 

What Is Pickleball? 

Congressman Joel Pritchard, Barney McCallum, and Bill Bell invented the game of pickleball one summer afternoon in 1965 on Bainbridge Island, WA as a fun activity for the whole family. Fast-forward to 2020, when the game’s popularity exploded across the U.S. as pandemic lockdowns as people craved exercise and community. 

Pickleball is a paddle sport that combines elements of tennis, badminton, and ping pong. It's typically played on a badminton-sized court with a modified tennis net, using solid paddles and a perforated plastic ball. The game can be played as singles or doubles and is known for its friendly and inclusive community.

The objective of pickleball is simple: to score points by hitting the ball over the net and into the opponent's court without letting it bounce twice. The game begins with a serve, which must be made underhand and diagonally across the court. Once the ball is in play, players continue to volley until a point is scored or a fault is committed.

Basic Rules and Gameplay

Pickleball follows a set of straightforward rules to ensure fair play and enjoyable competition. Some key rules include:

  • The non-volley zone, also known as “the Kitchen”, restricts players from hitting the ball while standing inside it.
  • The serve must land within the opposite diagonal court and clear the non-volley zone.
  • The ball must bounce once on each side of the net before players can begin volleying.
  • Points can only be scored by the serving team.

Equipment and Attire

One of the appeals of pickleball is its minimal equipment requirements. All you need to get started are a paddle, a ball, and a pair of comfortable court shoes. Pickleball paddles come in a variety of materials and designs, so it's worth trying out different options to find one that suits your playing style. As for attire, breathable and moisture-wicking clothing is recommended, along with hats and sunglasses for outdoor play.

Tracking Your Skill Level and Player Rating

In pickleball, player ratings are used to assess skill levels and ensure balanced matches. The DUPR (Dynamic Universal Pickleball Rating) system is the most accurate and widely adopted pickleball rating system in the sport. Once you download the app and create an account (for free), DUPR takes into account your performance against opponents of varying skill levels, across recreational, club and league matches. With a personalized DUPR-score, you have a pickleball rating that reflects your abilities at any given moment.

How To Improve Your Game

Whether you're a beginner or a seasoned player, there are always ways to improve your pickleball skills. Here are a few tips to help you level up your game:

  • Practice regularly: Like any sport, consistent practice is key to improvement. Set aside time to work on your serves, volleys, and footwork.
  • Take lessons: Consider taking lessons from a certified pickleball instructor to learn proper technique and strategy.
  • Watch and learn: Watching videos of professional pickleball matches can provide valuable insights into tactics and gameplay.
  • Play with better players: Playing against opponents who are more skilled than you can challenge you to elevate your game and adapt to different styles of play.
  • Have fun: Above all, remember that pickleball is meant to be enjoyable. Don't be too hard on yourself and focus on having fun and making new friends on the court.

Paths to Reliability: How to Achieve a 60% Reliability Score…and Progress to 100%

The DUPR Reliability Score gives players more insight into how close they are to achieving a reliable rating. If your Reliability Score is above 60%, your rating is reliable, and you can be confident that you’ll have a competitive experience playing with others at a similar level. If you’re under 60%, whether that’s because you’re a new player, or you haven’t played in a while, it means you have more playing to do! But don’t worry, there are a variety of ways to reach a 60% Reliability Score, and, for overachievers, progress from 60% to 100%. 

Here are some paths you can take to get a good reliability score. Each match represents one game. Matches with more games will count more and progress you to reliability faster because there will be more information input into the rating system. 

Remember, the biggest takeaways are playing frequently (and inputting your results!) and playing with a variety of players. 

Reliability Progression Paths 

Just starting out or have less than 10 games under your belt? Here’s how to get to a reliable rating (60% Reliability Score). 

These paths assume the following: 

  • Opposing player or team ratings are all within 0.5 of your player or team rating. 
  • Teammates and Opponents are reliable (ie have a 60% Reliability Score).
  • Matches are with 2 or more unique partners (Doubles only) and against 6 or more unique teams.
  • Matches are each one game.

Note - There are many ways to achieve a Reliability Score of 60% or higher. The biggest takeaway is more is better! Play more games, play more with similarly rated players, play more with players who are more reliable than you and play with a wide variety of players. Those are the key factors in improving your Reliability Score. 

Already have a reliable rating? Here’s how to achieve a 100% Reliability Score

These pathways assume:

  • Players and opposing teams are all a similar level (ie within a 0.5 range)
  • Teammates and Opponents have a 60% Reliability Score (or higher) 
  • Doubles matches are with 4 or more unique partners 
  • All matches are against 12 or more unique teams 
  • Matches are each 1 game 

Note - The biggest takeaway is more is better! Play more games, play more with similarly rated players, play more with players who are more reliable than you and play with a wide variety of players. Again, these are the key factors in increasing your Reliability Score.
