At 00:36 (first attack of Scavengers on Interceptors) there were 89795 Scavengers. With 7 damage per shot and 3x spec their total damage output would have been 1 885 695. But Interceptors have 20% chance to dodge a normal attack, so the average damage they should take is 80% of that, which is 1 508 556. And the actual damage was pretty much that:
00:36 Scavenger attack with firepower 1 508 304 (damage 0/1 508 304) Interceptor
The damage is a tiny bit off from average due to random nature of dodge mechanics, but otherwise in line with the expected value.
