How much damage reduction does bosses armor provde, so how much does cs amplify your damage?

You deals ~47% more damage against a 93lvl boss under CS than against a 93lvl boss without CS.
(That's just counting the armor, not the Slam buff.)

Armour reduction for 93 is 32%

93 armor: 24825
DamageReduction = TargetArmor / (TargetArmor + 4037.5*AttackerLevel – 317117.5)

24825 / (24825 + 4037.5*90-317117.5) = 0.3493
with sunders brings its to 32% damage reduction.

Let's say you deal 100k damage with a physical attack to a lvl93 boss without CS debuff. You'll deal 147k damage to this same boss with CS debuff.

That means you're dealing 47% more damage while CS is active.
That also means that his armor reduced the damage he received by 100% - (100k*100)/147k = 32%.

We are both correct.

They are both right.
As for haste/crit, I don't remember the exact plots ATM as I am at work but it is much lower than crit.
