We interpret Player Welfare as additionally applying tried and tested algorithms and analytics from Sports Science to data captured during the course of coordinating team activities and communications, presented in a clear, visual graphic. Key published papers for measures implemented in SURPASSPORT are listed below.
Known formally as "Acute : Chronic Workload Ratio" (A:CWR), this measure is used by elite teams to measure the consistency of activity. It is calculated from Arbitrary Units ("AU"s) of workload and compares such values for the current period when compared to the average over the preceding number of periods.
SURPASSPORT uses a measure of Activity Duration by Intensity, averaged over 7 days and compared to an Exponentially Weighted Moving Average over the preceding 30 days.

Known formally as the age of "Peak Height Velocity" (aPHV), this is the age of the individual when their body is growing the fastest, often referred to as their growth spurt during teenage years. It is calculated based on skeletal measurements including standing height; torso height and body weight.
SURPASSPORT also records arm span and knee height in preparation of additional confirmation of the age of peak height velocity.
