Each of those variables is scaled to a value between 0 and 2.375, with 1.0 being statistically average (based on league data between 1960 and 1970). When the formula was first created, a 66.7 rating indicated an average performance, and a 100+ rating indicated an excellent performance. [3]
The overall performance rating is then calculated as = +, the same as the FIDE method. An equivalent way to calculate this performance rating is by taking the average of opponent's rating + 400 for each win; opponent's rating - 400 for each loss; just their rating for each draw.
The Elo[ a] rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess or esports. It is named after its creator Arpad Elo, a Hungarian-American physics professor. The Elo system was invented as an improved chess-rating system over the previously used Harkness system, [ 1] but is also used as ...
The following Bayesian formula was initially used to calculate a weighted average score for the Top 250, though the formula has since changed: = + + where: = weighted rating = average rating for the movie as a number from 1 to 10 (mean) = (Rating)

If a player scores 50%, they receive the average competition rating as their performance rating. If they score more than 50%, their new rating is the competition average plus 10 points per percentage point exceeding 50. If they score less, their new rating is the competition average minus 10 points per percentage point shy of 50. [5]
Player efficiency rating. The player efficiency rating ( PER) is John Hollinger 's all-in-one basketball rating, which attempts to collect or boil down all of a player's contributions into one number. Using a detailed formula, Hollinger developed a system that rates every player's statistical performance. [ 1]
Net run rate ( NRR) is a statistical method used in analysing teamwork and/or performance in cricket. [ 1] It is the most commonly used method of ranking teams with equal points in limited overs league competitions, similar to goal difference in football . The NRR in a single game is the average runs per over that team scores, minus the average ...
