Engineers Hull modification stats wrong?

[Thetele]

So i rolled dice for heavy duty armour modification for my Python with lightweight alloy. And after roll i looked at stats. It list kinetic resistance -18.8 as Good and positive effect but should lose of kinetic resistance be negative and red instead of blue? Same with explosive resistance stat. If its upgrade shouldn't the resistance go up and not down?

That's a damn godly roll right there!

The number just means 18.8% DAMAGE REDUCTION. That's why it's negative

Default resistance for your normal/reinforced/military hull is -20% kinetic, so a kinetic shot hitting you for 1 damage would do 1.2 damage. Your roll means that a kinetic shot hitting you for 1 damage will now do 1.1904 damage instead.

Oh, good to hear. But should it say kinetic damage or something like that on stat instead of kinetic resistance.

It isn't a damage reduction it's a resistance reduction.

It is cause you are using Military armor. Everything fine. It just show your resistance over all after upgrade.

Well, looking at the scale I see it has "-20" on the red side (and "-40" to explosive). So -19 isn't how much it changed by, it's the new total. So it's listed as positive because it's less negative, if that makes sense. The actual change to your resistance value is +1 (from -20 to -19). Yes, the effects on tier 1 are pretty small.

I'm not sure if I really adequately explained it, but I hope the idea is there.
