Epley Advantage Index Reports include a Perfomance report called the Epley Advantage Performance Index or EAPI and a Strength report called the Epley Advantage Strength Index or EASI. These index reports are unique because they take into account the size of the athlete when giving a score of athleticism.
The EAPI uses three metrics – speed (10 or 40 yard dash), agility (5-10-5), and power (vertical or broad jump). If you were to look at two male athletes that ran a 4.75 sec 40 yard dash and one weighed 155 lbs and the other weighed 210 lbs, or the same two athletes both had a 30 in vertical – which one would be more impressive? It is obvious that the 210 lb athlete is more impressive here – as they are moving more mass, but a standard leaderboard does not account for this.
For reference, if they had the same time for the 5-10-5 (ProAgility) then the 210 lb athlete would have an EAPI score of 1202 where the 155 lb athlete would have a score 1040 – now we have an unbiased score of athleticism!
The algorithim behind this index is not something we are just pulling out of thin air. It was originally developed in the 1960’s by the “God Father of Strength & Conditioning” – Boyd Epley, his right hand man Mike Arthur, and University of Nebraska Statistics Professor Chris Eskridge. It has contined to evolve as decades of data have continued to make it more valuable.
Since integration with the Dashr platform, data from tens of thousands of athletes ranging from 8-30 years old have givin us the ability to share a national percentile rank in the report. A score of 900 is not great for an athlete who is 18 years old and trying to play D1 ball – but it is fantastic for someone that is 11 or 12. We are now able to better express what the scores mean without discouraging younger athletes.
The EASI report has a reverse relationship with wieght, the more mass you can move with respect to your weight – the better your score. So if the two athletes above both squatted 400 lbs 3 times (1RM = 436 lbs) and cleaned 250 lbs 4 times (1RM = 280 lbs) – the 155 lb athlete would have a higher index score (1166 vs 860).
