Elo windows 10 driver12/24/2022 I treat each race as a series of matchups between every single driver. WonMatchup is a 1 or 0 depending on if the driver beat their opponent in given matchup. For Ind圜ar, I found k=2.5 to be the most predictive. In baseball, where there are a lot of games, the k is lower than in football, for example. It essentially is a measure of how important each matchup is to the system and differs in every sport. K is the k-factor, which tells the ratings how much to update after each race. The OldRating is the driver’s Elo rating before the race. NewRating = OldRating + K(WonMatchup – ExpectedWinMatchup) The first part of this article will detail how the ratings are calculated, but feel free to skip past that for the results or come back to it later!Įlo ratings are updated after each race using the following formula: Elo ratings have a couple of great qualities that make them a good choice to rank and compare Ind圜ar drivers. Elo ratings were developed by Arpad Elo to rank chess players, but they have since been used to rank sports from soccer to football to basketball and more. This is a really fun article for me to write because one of my first “big goals” when I started writing about Ind圜ar statistics was to apply the Elo rating system to Ind圜ar drivers.
