Wild Frenzy does not effect fire rate at all

[(NSW)impendo]

When using the wild Frenzy mod on my prisma grakata, the alternate fire will shoot at the exact same rate as the primary fire. I'm using no other mods except for wild Frenzy. When I shoot with the primary fire, the magazine empties in 6 seconds, and the magazine empties in 6 seconds when shooting with the alternate fire. There does not seem to be any change in fire rate at all when shooting with the alternate fire even though the mod says it should shoot with 400% fire rate. I tested this in the similacrum with nidus.
