also due to how armor penetration is calculated (reduction first, penetration last) then if you have % arpen mastery (you do) the effectivity of all armor reduction is reduced by 10%. that means black cleaver actually provides only 40.5 armor reduction and only after three hits. while with last whisper and mastery you got 46% armor penetration vs any amount of armor that works on all hits.
