StartGGElo

StartGGElo is a tool for using start.gg's video game tournament data to generate and maintain Elo ratings for each competitive player.

Once Elo ratings are generated, StartGGElo can be used to generate ranking lists, predict the probability of a player winning a match, generate seedings for future tournaments, and more.

Configuration

StartGGElo stores its rating database in its config directory, which is located at:

• Windows: %APPDATA%\Roaming\ggelo
• Mac/Linux: ~/.config/ggelo or ~/.ggelo

This directory also contains StartGGElo's config file, which defines how it calculates its ratings.

Elo system basics

For more information on StartGGElo's rating system, see the details page.

As the name implies, StartGGElo uses the Elo system for its ratings. In the Elo system, all newcomers to the game are assigned an initial rating, and this rating is adjusted whenever a player loses or wins matches. The initial rating for StartGGElo is 1500, but this is configurable.

Whenever a player enters a tournament, StartGGElo will use start.gg's API to determine how many sets that player won within that tournament. This number is the player's score for that tournament. If the score the player earned is larger than their Elo rating would predict, then their rating is increased.
