About


What is the purpose of this project?

Using the latest information available, we approximate and project forward how teams may end up ranked in the next round of USAU's algorithmic rankings. We strive to provide these projections as quickly as possible after key games or tournaments have occurred. We also provide a number of related tools and resources to help you better understand the rankings algorithm and the factors that influence it.



What is the history of this project?

In 2025, Ultiworld teamed up with the creator of frisbee-rankings.com, Cody Mills, to bring his website and tools into the Ultiworld family. We are excited to provide a long-term home for this project and resources to make improvements in the future!

Here are a few words from the creator of the Projected Rankings website (formerly known as Frisbee Rankings):


Cody Mills, Creator of Frisbee Rankings

Hey, I'm Cody, and I enjoy ranking problems.

The site has grown a bit from its humble beginning as a display/breakdown of the USAU algorithm results—it now also supports a probabilistic bid allocation system (that works in conjunction with the USAU rankings) proposed in collaboration with Scott Dunham (aka Hallies_Dad).

In the near future I hope to add other types of algorithms to see how they might fare in the context of ultimate (Glicko2, Bradley-Terry, TrueSkill, and a maybe throwback to RRI). Current features under construction include a connectivity viualization and a simulator for sample results.

If there's anything you'd like to see or that you think might be helpful, let me know and I'll try to add it to the queue!

Here's some of my other work related to the intersection of ultimate and data:
