Glass Armor (chest + gloves + boots + helm (76 total) + 100% bonus from perks + 25% (of original total) all light bonus + 25% matching set bonus = grand total)
38 + 11 + 11 + 16 + 76 + 19 + 19 = 190 total
Dragonscale Armor (chest + gloves + boots + helm (82 total) + 100% bonus from perks + 25% (of original total) all light bonus + 25% matching set bonus = grand total)
41 + 12 + 12 + 17 + 82 + 20.5 + 20.5 = 205
Daedric Armor (chest + gloves + boots + helm (108 total) + 100% bonus from perks + 25% (of original total) all heavy bonus + 25% matching set bonus = grand total)
49 + 18 + 18 + 23 + 108 + 27 + 27 = 270
Is that math right? Anyway, this means that the best heavy armor in the game offer 25% more protection that the best light armor in the game. Or something. ha ha
