when placing a shield amplifier on my dropship, The first ward amplifier is supposed to add 15%, but it only adds 80% of the total effect. this continues to affect each one after, causing a massive change in total resistance.

I'm 99.98% sure that its because you're doing the math wrong. Really. If you have 10% resistance or whatever base, and you add a 15% mod, you're not supposed to get 25%. And its not because you're getting stacking penalized. Yes you're getting the full 15% effect too.

Did not realize that the stack starts at first mod in presence of base stat

It is worth noting, however, that if you already have some resistance due to skills/vehicle then the module won't add resistance in the manner you might expect.

For example:

You have 25% resistance due to skills. You apply a module that gives you 15% resistance. You will not end up with 40% resistance. You instead end up with 36.25%.

This is calculated by giving you a further 15% resistance of the 75% resistance that you have left. I.e. 75% * 15% = 11.25%. Add this to the 25% that you started with to get 36.25%.

It makes sense to do this, since otherwise it would be possible (with enough modules) to reach 100% resistance and receive zero damage. The Stacking Penalty merely exists to exacerbate the issue and ensure diminishing returns for all stacked modules (especially damage modules).

I did not realize that skills will act as a first mod, thanks for the imput

I can verify this, my tank has a passive shield resistance of 6% and a ward amp (15%) that should come to 21% but instead comes to 18.2, i'm glad someone else saw this.

That would mean that your module is getting the stacking penalty (of ~83% efficiency) even though it's a higher figure than your passive resist bonus. That's pretty terrible.

I've wondered about this myself, and you seem to know what you are talking about. So lf I may, can I verify using another example with a few questions?

Taking hacking speed reduction as the skill, with both mini Logi, and system hacking into account.

Does suite bonus x5 (25%) plus system hacking x5 (25%) = a total of 50% reduction?

Then if I add a complex code breaker (25%), does that = 25% off the remainding (50% if yes to above) or a total of 75% off the original total?

Thanks for your time.
