Decays works like armor
That means what counts is:
minimum decay due to total protection
damage absorbed
durability(to a much lesser extent
Therefore if your vehicle takes critical of 300 damage burn
will decay the same as if it had taken 1 hit of 1 damage burn
wil decay more if the damage taken is of 2 or more types and the protection granted (absorbed) is higher
For example, on a Quad-Wing Interceptor (L), damage by Kismet Light Laser (L) will be pure burn and will decay what 18 damage that were protected requires ~1.4 PEC
Assuming 8 shots that will cost 11,2 PEC
On the other hand if what used to shoot at it an VTOL MMB AS-35 (L)
Not only the number of shots required to fully damage the vehicle would be higher
So it would be the decay per shot
For an estimate I lets say the damage protected would be the maximum 48, which in this case requires ~5 PEC
Assuming 15 shoots that will cost 75 PEC
977 Quad-Wing Interceptor (L) 1 41.39 PED CARRIED
I have only been shot down once.
narfi
Which as you see is compatible with real cases (48 damage would be an overestimate of protection per shoot in case you didn't notice I make it clear now)
Valkyrie Mk1 (C,L)
Total damage protection: 81
Minimum decay per hit: 0.81 PEC
Minimum damage absorbed to do more than minimum decay: ~12
Burn protection: 8 so if tested against a gun that does only burn it will have minimun decay per shoot.
Against large I+C+S mob protection: 34 so about 3,2 PEC decay per hit
