ROCCAT Elo 7.1 Air Wireless Gaming Headset Review

If you have played any sort of competitive game recently, you might be wondering how their matchmaking systems work online. Many games use a rating system based on the Elo rating system, which ranks people relatively based on their individual statistics.

Invented by Arpad Elo, this sort of ranking methodology was first invented to rank players against others in competitive chess.

This method assumes that performance is normally distributed, while each individual’s ranking is their average performance over time.

Players will be therefore ranked and play against others of a similar ranking. The Elo rating system should also predict the outcome of the match too. T

here are also variations or modifications to implement Elo’s general ideas, such as Glicko-2, which is used in Counter Strike: Global Offensive.

However, most people still refer to all of these variants as Elo. There are still some issues with Elo ratings such as rating inflation and deflation or protection of ratings.
