I am trying to calculate the chance that a ship will be jammed by a flight of ECM drones. Difficulty is coming from stack penalty.
To start we need some numbers to work with. Lets say a Drake deploys 5 small ECM drones against a Rupture that has sensor strength of 12. Small drones have strength of 1, but are stack penalized. Therefore:
Drone 1 Jam Chance: 1.0000 / 12 = 0.0833
Drone 2 Jam Chance: 0.8691 / 12 = 0.0724
Drone 3 Jam Chance: 0.5710 / 12 = 0.0476
Drone 4 Jam Chance: 0.2825 / 12 = 0.0235
Drone 5 Jam Chance: 0.1060 / 12 = 0.0088
That is all well and good, but now comes the question: What is the chance that at least one of these five drones get a jam in one cycle?
Now if the chance of each individual drone was the same, the result is easy: Chance would be 1 - (1 - jam strength / 12) ^ 5. Alas due to the stacking that is not the case. How do you work it out in this case?

They aren't stack penalised. ECM is chance based and so are the drones. Treat them the same as 5 ECM modules, although that isn't exactly true as they may not all be in range - closest you'll get though.
All the other damping/webbing/TD/etc drones are stack penalised just like modules because if they are in range they WILL work. ECM drones may not and hence aren't stack penalised.

Is that confirmed anywhere? This would make ECM drones overpowered beyond belief!

It's pretty much common knowledge and it just means that the other EW drones are somewhat useless and you should never use full flights of them. If you plan to use EW drones other than ECM, use a mix of several different EW types or mix them with damage drones.

You can test it yourself if you stagger the drones on a stationary alt. You have to release the drones one at a time so they behave like ECM modules (eg overlapping cycles) if you see what I mean? Edit - I tested this 18 months or so ago, just left log to run overnight with 4 drones I think. Its the same chance as if it was 4 very weak ECM mods fitted to your ship doing the jamming.
In practice (exploit excluded) its virtually impossible to get any cycle jamming going as all the drones activate on target immediately, so you effectively MIGHT get a 20 second jam then you'll get nothing for ages.
Stack penalties on a chance based system don't make any sense

This about it this way.
How can an ECM module be stack penalized?
It can't.
It's either jam or no jam.
It's not like a TD where a second applied TD would do less disrupting than the first one, you either get a jam or not regardless of what other ECMs are doing.
So if one ECM module or ECM drone has a 30% chance of jamming, for 5 of them its going to be
30% jamming chance for each one
not
30% for the first one 26.2% for the second 20% for the third... etc
