of level only on completion of shuttles. The Léger test's algorithm requires that each level lasts approximately 60 seconds. This means the next level commences when the absolute difference between the time spent at the level and 60 seconds is least. Put simply, some levels may run for a trifle less than 60 seconds, others a little more than 60 seconds and the odd one exactly 60 seconds. On the other hand, a few non-Léger versions of the test trigger a level change only when the time spent at a level first exceeds 60 seconds. This variation results in one extra shuttle being run at some levels. In practice, since the speed change at a new level (rather than an extra lap) is most likely to trigger "failure", this variation also has an insignificant change on one's achievable score. Scoring starts from zero Scoring of the Léger test starts from 1. That is, at the end of the very first shuttle, the participant has scored 1.1. A variation has scoring starting from 0; at the end of the first shuttle, the runner has achieved 0.1. The impact of this variation is purely administrative: just add or subtract 1 to convert scores. World record Participation The Guinness World Record for the largest group beep test is held by Army Foundation College, in Harrogate, North Yorkshire; 941 people took part. In popular culture The introductory explanation of one multi-stage fitness test, the FitnessGram PACER test, has been widely spread as a copypasta, meme, and through other comedic ways due to the test's modern use in schools, primarily in physical education classes.
