When you do the Unfathomable Depths quest, you'll get a set-bonus upgrade. Whenever you wear a full Dwarven Armour after that quest, you get a bonus on top of total armour rating of 25%.

Orcish Armor = 120

Dwarven Armor = 104

Dwarven Armor (post-quest) = 130

I'll adjust the page accordingly, whoever wrote it may have been more vague than they intended. If 25% brings it to 130, it would even surpass Ebony Armor, so, yea.
