Does more mean percentage total or percentage change?
Sorry, I just looked at correct "More"
We are looking at that one, right?
You gave the reason, you've said all weapons are affected equally by the bug. So yeah, if that's true, better hit ratios will be affected more.
That would mean percentage of total, ie case 1 has twice as many (on target) duds
case 1:
100 rounds fired. 30 hits. 6 duds
case 2
100 rounds fired. 15 hits. 3 duds.
But with diff rounds we get diff picture (in some cases)
Scenario
Small samples (simplified):
lets say 100 50cals equals 1 30mm (and also takes same amount to kill target ie 100x50cal rounds or 1x30mm)
lets say dud percentage is 10 in both types of ammo
50 cals
I fire 100 rounds at target, 90 do damage. I have to fire 10 more rounds, no damage. I fire 10 more. One dud. Fire 1 more. Target killed. Had to fire 121% of rounds
30mm A
I fire 1 round, no kill, I have to fire 1 more round. Target killed. Had to fire 200% rounds
Now if both types would be fired equal amount that would average out over long period of time (same dud percentage)
But 30mm is more lethal, it will always be fired less than 50cal. and deviation from average (among individuals) will always be more (Law of Probability).
