13 seconds activity time for a 5 minute match spent dogfighting planes?

How does activity time work? Do I only get activity time when my bullets hit a player or what?

Elapsed mission time is considered “active” if you hit an enemy, got hit, or performed a mission task such as destroying ai targets, bombing bases, capturing points, etc. If you are not hitting something or getting hit, you will not get credit even if you are in the middle of combat.

if i recall it use to be if you were just near an enemy it would give activity time but due to bots and other shall we call it unfair gameplay gaijin changed it to time actively contributing to the mission like achieving hits and etc
