Possible bug with status chance of Ballistica Prime, Mara, Mara Detron

[-SD-Nikarkos]

The Ballistica Prime, Mara and Mara Detron do not scale normal with status chance mods.
These are the Stats of the Ballistica Prime:
    Standart: 20%
    Frostbite: 30.5% = 11.5% incease
    Frostbite + Jolt: 39.9% = 9.4% increase
    Frostbite + Jolt + Scorch: 48.3 = 8.4% increase
    Frostbite + jolt + scorch + pistol pestilence: 55.8% = 7.5 % increase
With every mod the amount gets smaller even tho it schould be a 60% increase from the standart status chance every time. (At least thats how every other weapon behaves)

Weapons that are really simmilar like the Brakk behave normal.

if i´m correct these two formulars are the ones interesting here:

Chance per Pellet = 1 − (1 − Status Chance × Status Multipliers)^{(1 ÷ Base Number of Pellets)}

Listed Status Chance = 1 − (1 − Chance per Pellet)^{Modified Number of Pellets}

 

So this should be the result

1 - ( 1 - 0.2 * (1 + 0.6 + 0.6 + 0.6 + 0.6)) ^ (1 / 4) = 0.247879 no multishot mods installed

1 - ( 1 - 0.247879) ^ 4 = 0.68 = 68% So it should be 68%

Even tho it shows 55.8% in my arsenal.
