Each player has an ELO rating, which is a numerical value representing their estimated skill level compared to other players. Ratings adjust after each race. Winning against a player with a higher ELO rating increases your rating significantly, while losing to a player with a lower rating decreases it.

The size of your ELO change depends on three factors. First, the difference between your ELO and your opponent's. The larger the gap, the more your rating can shift. Second, the outcome of the race, where winning yields more points than a draw, and losing costs more. Third, the K-factor, a constant that determines the maximum change per race. The K-factor is usually lower for high-rated players and higher for low-rated players.

ELO helps match players of similar skill levels, making races more competitive and exciting. It also allows players to track their improvement over time and creates meaningful leaderboards and rankings.

The exact formula can vary, but the basic principles remain the same. Your new ELO rating is calculated based on your current rating, your opponent's rating, the race outcome, and the K-factor.

Example: If you have an ELO of 1500 and win against a player rated 1600 with a K-factor of 32, your rating would increase by several tens of points.

ELO is relative. It shows how skilled you are compared to other players within the same system. It is not perfect, as factors like luck, technical issues, or specific race conditions can influence outcomes. Your rating is dynamic and will fluctuate based on your performance.
