What is both the most efficient way to reach the cap of 85% physical damage reduction (567 Armor)?
Can it be reached without smithing/enchanting perks? Is it more efficient to not get some smithing or enchanting perks and just get heavy armor perks? Or is there some combination of crafting and heavy armor perks that gets to 567 armor with a smaller investment of perk points?
For purposes of this question, most efficient is defined as the smallest possible amount of perks used to acquire the stated physical damage reduction, passively - i.e. without popping pots (temporary) or using extra buffs from stones, blessings, or +Heavy Armor skill enchants (to keep those slots on equipment free for other enhancements). Also, any skill used to achieve this can be assumed to be leveled to 100 (for example Heavy Armor could be assumed to be already leveled to 100).
