Note: A circuit consists of running two shuttles followed by a 10 second rest period Table derived from "The Yo-Yo Intermittent Tests: A Systematic Review and Structured Compendium of Test Results" [4] and ESPNCricinfo [6] As a side note, "Speed Level" correlates exactly with "Running Speed (km/h)" using the formula: (Running Speed – 7.5) * 2.
The Léger test requires the first level to be run at 8.5 km/h. Some organizations require it to be run at 8.0 km/h. Note that the second level is always [4] run at 9.0 km/h. Also, speeds at subsequent levels always increment by 0.5 km/h. The impact of this variation is insignificant as almost all runners' scores easily exceed level 1.
0 if the rankings are completely independent. −1 if the disagreement between the two rankings is perfect; one ranking is the reverse of the other. Following Diaconis (1988), a ranking can be seen as a permutation of a set of objects. Thus we can look at observed rankings as data obtained when the sample space is (identified with) a symmetric ...

U.S. Soccer refused to sanction either the First Division or the new NASL for 2010, and the two groups eventually agreed to unite for 2010 only under the banner of USSF Division 2, run directly by U.S. Soccer and including teams from both leagues. U.S. Soccer initially sanctioned the new NASL in November 2010, revoked its sanctioning in January ...
The CAF 5-year ranking system is used by the Confederation of African Football (CAF) to determine the number of clubs that each member association may enter its club football competitions; the CAF Champions League and the CAF Confederation Cup. At present, those associations ranked in the top 12 may enter two teams into each of the two club ...
Passer rating (also known as passing efficiency in college football) is a measure of the performance of passers, primarily quarterbacks, in gridiron football. [1] There are two formulas currently in use: one used by both the National Football League (NFL) and Canadian Football League (CFL), and the other used in NCAA football.
Initially the correlation between the formula and actual winning percentage was simply an experimental observation. In 2003, Hein Hundal provided an inexact derivation of the formula and showed that the Pythagorean exponent was approximately 2/(σ √ π) where σ was the standard deviation of runs scored by all teams divided by the average number of runs scored.
