An example may help clarify. Suppose Player A Le matchmaking lol a rating of and plays in a five-round tournament.
He loses to a player rateddraws with a player rateddefeats a player rateddefeats a player ratedand loses to a player rated The expected score, calculated according to the formula above, was 0. Note that while two wins, two losses, and one draw may seem like a par score, it is worse than expected for Player A because their opponents were lower rated on average.
Therefore, Player A is slightly penalized. New players are assigned provisional ratings, which are adjusted more drastically than established ratings. The principles used in these rating systems can be used for rating other competitions—for instance, international football matches.
See Go rating with Elo for more. Mathematical issues[ edit ] There are three main mathematical concerns relating to the original work of Elo, namely the correct curve, the correct K-factor, and the provisional Le matchmaking lol crude calculations.
They found that this did not accurately represent the actual results achieved, particularly by the lower rated players. Instead they switched to a logistic distribution model, which the USCF found provided a better fit for the actual results achieved. FIDE also uses an approximation to the logistic distribution.
If the K-factor coefficient is set too large, there will be too much sensitivity to just a few, recent events, in terms of a large number of points exchanged in each game. Too low a K-value, and the sensitivity will be minimal, and the system will not respond quickly enough to changes in a player's actual level of performance.
Elo's original K-factor estimation was made without the benefit of huge databases and statistical evidence. Sonas indicates that a K-factor of 24 for players rated above may be more accurate both as a predictive tool of future performance, and also more sensitive to performance.
The USCF which makes use of a logistic distribution as opposed to a normal distribution has staggered the K-factor according to three main rating ranges of: K-factor of 32 used Players between and K-factor of 24 used Players above K-factor of 16 used.
FIDE uses the following ranges: Thereafter it remains permanently at FIDE used the following ranges before July The gradation of the K-factor reduces ratings changes at the top end of the rating spectrum, reducing the possibility for rapid ratings inflation or deflation for those with a low K factor.
This might in theory apply equally to an online chess site or over-the-board players, since it is more difficult for players to get much higher ratings when their K-factor is reduced.
Practical issues[ edit ] Game activity versus protecting one's rating[ edit ] In some cases the rating system can discourage game activity for players who wish to protect their rating.
