Is it still 567 armor?

Before I installed a bunch of mods to make enemies in Skyrim scale much harder and my own abilities scale much weaker in order to provide a suitable challenge, I remember one of my biggest peeves about the game's balancing was the armor cap of 567 (80% DR), since you could easily reach it even in light armor with sufficient improvements and perks (even without using the alchemy/enchanting/smithing infinite combo).

Still 567, but like you said, its possible one of your mods changed the value.

It's technically 667, but every piece of armor carries a 25pt hidden rating.

so wearing 4 pieces, it's 567.

Never heard of that.
