How it is calculated
Three conditions must hold. The combined acceleration on all three axes is above 5.7 g. The player's top speed in the second before was at least 1.5 m/s. Their speed then drops by at least 0.83 m/s, about 3 km/h, within two seconds.
After each impact the app waits three seconds before it counts another, so one collision is counted once.
For each impact it also records the distance the player travelled after contact.
How to read it
Impact counts matter most in contact sports. Use collision load to see how severe the contacts were, not just how many there were.
Questions
Why does the player need to be moving?
It separates contacts from the pod being dropped, knocked or handled while the player stands still.
