Ultimate ELO

Ultimate Top 8 ELO is based on the Elo rating system, developed by Dr. Arpad Elo. This system is used by FIDE, the international chess federation, to rate chess players.

UltimateElo.com applies the Elo rating system to international SSBU Top 8 head-to-head matches in major competitive tournaments, by adding a weighting for the kind of tournament, as defined by the Liquipedia Ultimate page, and calculating new ratings for winners and losers.

The ratings take into account all international matches in Top 8 for which results could be found via Start.gg. All players that enter a major top 8 for the first time start with a 1500 rating. This number is arbitrary but is applied to all players entering their first top 8. Winning grands in one set or two sets counts as a win for the head to head. Resetting the finals does not affect ELO, only winning grands can affect the ELO.

Ratings tend to converge on a player’s true strength relative to their competitors after about 30 Top 8 matches. Ratings for players with fewer than 30 matches in Top 8 should be considered provisional. (This information is not currently provided.)

The ratings are based on the following formulas:

Rn = Ro + K × (W – We)

Rn is the new rating, Ro is the old (pre-match) rating.

K is the weight constant for the tournament played:

  • 60 for Supermajor Grand Finals;
  • 50 for Major Grand Finals;
  • 40 for Supermajor Top 8 matches;
  • 30 for Major Top 8 matches

 

W is the result of the game (1 for a win, and 0 for a loss).

We is the expected result (win expectancy), from the following formula:

We = 1 / (1 + 10(-dr/400))

dr equals the difference in ratings.

The ELO rating process is semi-automated. It is therefore susceptible to errors and will not update automatically.

This ELO was created as a way to further debate the skills of the top players worldwide. This is not a definitive metric of anyone. Those who are ranked low on the ELO list would still wipe the floor with 99% of the average smash players. Making a Top 8 at a major is worthy of praise only.
