Question about vet-level enemy defenses

AdicusDio

I've read they have something like 18200 defense? If that's the case, does high penetration negate that? Say I have 4000 penetration (just for example), would it work out as
18200-4000=14200 as the defense?

Royaji

Yes. And every point in penetration after 18200 is useless.

Thanks.

So why did my sharpened spriggan maul with kraghs with tfs not do much dmg
