Armor penetration perk from ACC (40) is not working at all.
How i tested it: take a bow (dragon) it have 9% arm pen + snake arrows (16% pen). Deal damage. Than add upgrade for extra armor penetration (+~13%, so in total it is ~35%) damage has not changed (before it was 61 and after it was 61).
When i add DAMAGE upgrade i receive ~+7-8 damage bonus per hit to the player.
INC ACC to 40 (39 before) - test again same way = no differance
Than tested it with melee weapon. AP bonus increase damage for spear ~+9 points, Damage bonus provide ~+7 damage points bonus. INC ACC to 40 test again = no differance
