"The silent ignoring of an amount of armor still results in a quantity of armor that does not benefit from a 20% increase, entirely due to the order in which the arithmetic operations are applied."

You clearly do not know what that order is, judging by your responses here.

Reduction: Armor > Flat Reduction > % Reduction > Courage Bonus

Penetration: Armor > Courage Bonus > % Penetration > Flat Penetration

Penetration has no effect whatsoever on Garen's W and it is not any more effective against him than anyone else because of it.
