Are these calculations correct? Please correct me if I am wrong

This is all just about Armor pen and all that jazz just wanted to display calculations and see if I was correct. Let's get into it.

So we have max lethality : Duskblade = 15 Lethality Ghostblade = 15 Lethality Edge of Night = 15 Lethality Serrated Dirk = 10 Lethality Runes = 24 Lethality Masteries = 6 Lethality

Total Lethality = 85 Lethality

We also have Black Cleaver and Lord Dom's

Cleaver = 30% Armor Reduction (obviously after its fully charged) *disclaimer, for the sake of my sanity I will say cleaver is fully charged 100% of the time and always at 30% armor reduction.

Lord Dom's= 45% Bonus armor penetration

Meaning. We have 30% Armor reduction (Percent) 45% Bonus Armor Penetration (Percent) 85 Lethality

The way armor pen works obviously everyone knows is.

1. Armor reduction flat
2. Armor reduction percentage
3. Armor penetration percentage
4. Lethality

We are facing a 300 armor target for this example or test with a base armor = 80 and bonus armor = 220 (Also again cleaver will automatically be fully charged up for this example)

Now, let us go in the order of Armor pen.

1. Armor reduction flat. We have 0 so NEXT.
2. Armor reduction percentage. (Cleaver) We have 30% Armor reduction.

Calculate. Cleaver effects base as well as bonus. so the algorithm will be. (base armor x 0.70) + (bonus armor x 0.70) = Amount of armor after reduction.

(80 x 0.70) (220 x 0.70) =56 =154

56 + 154 = 210 armor.

So we have 210 Armor as of right now. (after reduction from cleaver)

Base armor = 56 Bonus armor = 154

Back to the order of armor pen

3. Armor penetration percentage (Lord dom's) We have 45% Armor Penetration percentage.

However with lord dom's it only effects Bonus Armor. (It will only affect our targets bonus armor of 154)

Calculate. Lord dom's will only affect bonus. so the algorithm will be. (bonus armor x 0.55) = Amount of bonus armor after Penetration percentage.

(154 x 0.55) =84.7 = 85 Bonus armor

Now our target has Bonus armor = 85 Base armor = 56 Total armor = 141

Last but not least lethality.

4. Lethality Total lethality = 85.

141 - 85 = 56 Armor.

Targets armor after full cleaver charge up is. 56 Armor from 300.

Is this correct?

And yes I do know this means no boots.
