They are the same as in EVE.

This is what im going on, there is no for sure way to know, as of now though its the only info we have to go on.

No way to know for sure? Sure there is, and it's 100% confirmed that they are the same as in EVE.

Grab a calculator.
Buy a shield or armor militia vehicle.
Buy some militia damage resistance modules for 10% each.
It will tell u total damage resistance for armor & shield so just do the math yourself after each module you put on.

I stacked 3 basic rechargers (15% each).

The first 2 gave me 30% increase at 32.5 shield recharge: 25 x 0.30 + 25 = 32.5

But then I equip a third one and it gave 35.28 shield recharge. I can see a stacking penalty here because that's a 41.1% increase instead of 45%, but it's clearly not the same as EVE. The third module is giving more than 60% effectiveness.

Using EVE's stacking penalty numbers:

25 * 1.15 * 1.1305 (87% of 15%) * 1.0855 (57% of 15%) = 32.28.

We all know the numbers from eve ben, at least most of us, but where is this 100% confirmed bro.. id really like to know.

Using EVE's stacking penalty numbers:

25 * 1.15 * 1.1305 (87% of 15%) * 1.0855 (57% of 15%) = 32.28.

32.28 =/= 35.28

Did someone make a typo or is this still a mystery?

the math is harder with resistance mods. Most people seem to think that without stacking penalties 2 10% resistance mods would result in 20% increased resistance.

Do it with cardio regulators instead. Less chance you'll mess it up.

Also the UI isn't necessarily truthful, and the stacking mods aren't necessarily correctly applied (I'm looking at you, ferroscale/reactive plates).

Ok thanks. Seems like the stacking penalties start after equipping the third module and it applies to the second module as well. Thanks again.

No, there is a stacking penalty on the second module as well, as you can see in the calculations.

don't do this^
resistance stack against itself as well as stacking penalties, while damage mods don't.


this is correct
S(n) = 0.5^[((n-1) / 2.22292081) ^2]
or use this

Hey you know about tanks what's happening with the damage resistance is it bugged or did I make a wrong calculation.

Everything confirms the penalties are the same as EVE. When it comes to resistance mods it's all the same too, only thing to remember with them is the penalty is applied in the opposite order when using modules of different values.

If you use a 10% damage mod and a 5% damage mod the penalty will be applied to the 5%. But with a 10% resistance mod and a 5% resistance mod the penalty will be applied to the 10% mod.

EDIT: I should also mention that's the way they work in EVE as well.

Only think i know that stacking more than 2 is pointless in most cases, except for some exceptions, like Sniping with "weapon upgrades" for example, you don't really need shields for Sniping so you can stack 3 or 4 weapon upgrades and still benefit from it... but as an Assault stacking more than 2 weapon upgrades is useless, because you will benefit allot more from shields.

do some testing in game its really the only way to tell, frankly CCP doesn't have a clue, there is so much in this game they are missing a lot that is not working as intended, the only way to be sure is to test it in a match and not rely on the fitting ui.
