Sometimes you may notice NPCs fire faster than they should.
In this video I show 2 examples of such case.
For reference, normal fire interval for assault rifle is 0.158 seconds,
for minigun it is 0.020 seconds.
Now let's measure fire interval for this bugged case.
In the first example time between first 5 shots is about 3 seconds,
which makes it 3/4 x 5% = 0.0375 seconds fire interval,
which is more than 4 times faster than the normal fire rate.
In the second example time between first 13 shots is about 7 seconds,
which makes it 7/12 x 5% = 0.02917 seconds fire interval,
which is more than 5 times faster than the normal fire rate.
