Metrics Versions Release Notes

What are Metrics Versions and how do they affect each metric?

We're always looking for ways to improve the accuracy of the metrics we provide and occasionally we want to make changes to how we calculate things. In order to do this smoothly we've introduced metrics versions to ensure that when we do make a change it's clear what's changed.

In the mobile app you can see what version you're on by scrolling to the bottom of the settings page.

When a session has been created with a metrics version that differs to the one you're currently on, it will show you the version tag.

Below you will find a list of the metrics versions and an explanation of what each means.

Version 1.0.0 

Calculated Averages

Averages are calculated by summing the values of the contributing numbers and dividing by the number of contributing numbers. 

Total Distance

The total ground a player covers during a session. Calculated as the cumulative distance between successive GPS latitude and longitude measurements.

Max Speed

The player's peak running speed. Determined by analysing peak speed data in 0.5 second intervals to capture the maximum value.

Acceleration Events

Efforts of rapid increases in speed. Counted when the acceleration exceeds 2.25 m/s² for a duration of at least 0.5 seconds.

Deceleration Events

Efforts of rapid decreases in speed. Counted when the acceleration drops below -2.25 m/s² for at least 0.5 seconds.

Metres Per Minute

Represents the player's average pace of movement per minute. Calculated by dividing the player's total distance by the session's duration.

High Intensity Distance

The distance covered by a player in the 'High Intensity Running' zone. Calculated as the cumulative distance where the player's speed lies within the 'High Intensity Running' boundaries.

Sprint Distance

The distance covered by a player in the 'Sprinting' zone. Calculated as the cumulative distance where the player's speed exceeds a predefined 'Sprinting' boundary.

High Intensity Events

High Intensity Running' efforts. Counted when a player's speed remains within the 'High Intensity Running' boundaries for at least 1 second.

Sprint Events

'Sprinting' efforts. Counted when a player's speed surpasses the 'Sprinting' boundary and is sustained for at least 1 second.
 

Version 2.0.0 - Released in November 2023

Calculated Averages

Average calculation for an athlete's individual metrics remains the same as before. Team average calculation now takes the individual player's contributing seconds into account. 

Total Distance  [no change]

The total ground a player covers during a session. Calculated as the cumulative distance between successive GPS latitude and longitude measurements.

Max Speed [no change]

The player's peak running speed. Determined by analysing peak speed data in 0.5 second intervals to capture the maximum value.

Acceleration Events [no change]

Efforts of rapid increases in speed. Counted when the acceleration exceeds 2.25 m/s² for a duration of at least 0.5 seconds.

Deceleration Events [no change]

Efforts of rapid decreases in speed. Counted when the acceleration drops below -2.25 m/s² for at least 0.5 seconds. 

Metres Per Minute

Represents the player's average pace of movement per minute. Calculated by dividing the player's total distance by the time spent on the pitch.

High Intensity Distance

The distance covered by a player in the 'High Intensity Running' zone. Calculated as the cumulative distance where the player's speed lies within the 'High Intensity Running' boundary for at least 0.5 seconds.

Sprint Distance

The distance covered by a player in the 'Sprinting' zone. Calculated as the cumulative distance where the player's speed exceeds a predefined 'Sprinting' boundary for at least 0.5 seconds.

High Intensity Events

'High Intensity Running' efforts. Counted when a player's speed remains within the 'High Intensity Running' boundaries for at least 0.5 seconds.

Sprint Events

'Sprinting' efforts. Counted when a player's speed surpasses the 'Sprinting' boundary and is sustained for at least 0.5 seconds.
