Most champs have 30 magic resistance base... If I am trying to maximize my damage assuming Sorc Boots and Archaic Knowledge I should shoot for 5.5 magic pen?

30 *.15 = 4.5...(Archaic applies first right?) then 30 - 20 - 4.5 = 5.5?

So I should have 6 magic pen marks giving me 5.7 magic pen?

I see most folks using all 9 slots for magic pen is that a waste or are people calculating the 6 from the defensive tree? Or am I missing something entirely?

By the time you get your sorc boots there's a good chance they have mercs, raising their MR. Also even on many of my carries I use flat MR blues. So if you want to only handle the case where you're going against someone with ONLY base MR and nothing else at the point in the game where you only have sorc boots then yes, only use 6.

% penetrations always apply LAST. Reductions apply as such:

Flat Reduction (Abyssal, Fiddle, Ryze, Jarvan, ect...)
% Reduction (Nidalee is the only one who does this I think)
Flat Penetration (Runes, Haunting, Sorc)
% Penetration (Void, Last Whisper, Archaic)
