Liquipedia Rating: Current

Explanation[edit]

What is it?[edit]

Our main goal was to create a rating of all the teams that is based purely on data and therefore not subjective. The rating should reflect the current form of a team and make it possible to rank teams accordingly. In addition we also want it to be able to do this across regions with at least somewhat precise results. This is where LPRating comes in!

How does it work?[edit]

There are a lot of rating algorithms out there with probably the most prominent one being Elo. Elo was developed by Arpad Elo in 1960 to create an objective rating algorithm for the US chess federation USCF. It proved to be so successful that it was subsequently used worldwide. So, is LPRating just another iteration of Elo?

A little bit, but not quite.

Elo is a really interesting algorithm which fits for a lot of sports, but for numerous reasons, it doesn't fully work for Rocket League:

  • Elo is so accurate because so many players are ranked. Rocket League in comparison has a very limited number of teams that are consistently playing matches and appear in our database. Mostly RLCS, RLRS and some bubble teams from each region, but nothing compared to 360,000+ in chess rating.
  • Elo needs teams to play each other often and needs enough matches across skill gaps and regions. In Rocket League, especially cross regional tournaments are rare.
  • Elo is based on the assumption that a contenders skill is fairly constant, at least over short periods of time. In Rocket League, form can drastically change quickly. Even daily form can make the difference of a low tier team beating the higher tier one.
  • Elo always has even win- and loss-modifiers, which means that every point gained by a team is the loss of another one. Looking at Rocket League, this would create a problem for teams in Premier tournaments like RLCS. If the rating is designed to react to form fast, teams could potentially lose a lot of points during a season to allow gains for in form teams - but a team going 1-6 in RLCS is still probably top 10 in their region.

Considering these constraints, we made several changes to the Elo-Alogrithm to allow rating Rocket League in a more accurate fashion, which all come together as the LPRating.

Which results are included?[edit]

The LPRating includes the 3500 most recently played matches on Liquipedia. All tiers above Qualifier are included, but higher tiers like Premier (RLCS, ELEAGUE) and Major (RLRS, DreamHack) are given more weight.

Why does the first team always have 3000 points?[edit]

The rating is normalized. This means the best team has a fixed number of points (which is 3000) while the ratings of the other teams are scaled in proportion to that.
