Corrupted Mods have Equal Drop Chance in All Derelict Nodes?

Looking for Narrow Minded, Transient Fortitude and Fleeting Expertise.

Run Orokin Derelict Exterminate 25 times so far.

Not got one of those mods.  I do, however, have 4 vile accelerations, 4 vicious spreads, 4 tainted clips, and duplicates of several other less useful mods.  I already have Blind Rage and Overextended from before I started counting runs.

Does Exterminate even drop these mods?   Or are you supposed to look in a variety of derelict missions?  I like Exterminate because the vault is usually easy to find (unlike Capture).  The wiki says the drop chance of all mods are equal, which means - I think - I have a 13% chance per vault of getting ONE of these three (3 divided by 23).  Either I am super unlucky or the drop chance is not equal.

4.35% Chance according to the drop table. I've seen some interesting pool results from Vault runs but they should be equal.

For years Spoiled Strike was on the loot table twice. It was annoying. Any Vault drops all available mods.

It's just RNG, I had duplicates of all of them before I finally got the Vile Acceleration I was after.
