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

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: 

FAQs

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.
