How it is calculated
Collision load = Σ (impacts in band × band weight)
- 3 to 5 g counts 4. 5 to 10 g counts 7.5. 10 to 15 g counts 12.5. 15 to 20 g counts 17.5. Above 20 g counts 25.
- Each weight is the middle of its band. The top band has no upper limit, so it uses 25.
The app sorts each impact into a band by its peak g-force and adds up the band weights.
Pod impacts start at 5.7 g, so the 3 to 5 g band is empty for pod data. Imported Catapult and PlayerTek sessions fill it.
How to read it
Contact and running tax a player differently. A heavy-contact session can look light on distance, and collision load shows it.
The weighting is linear, so a 20 g hit counts about as much as five 4 g knocks.
Keep in mind
Collision load is shown as not measured when severity is unknown: non-contact sports, sessions with no impact data, and STATSports imports, which report a count without severity.
