Blood DK Mitigation

[:1]This is for a PvP Blood DK specifically, but I suppose the idea is relevant for really all classes, in both game types. Basically what I am asking is; am I doing this right?

For example:

Resilience: Reduces 40% of damage
Armor: Reduces 60% of damage
Blood Presence: Reduces 8% of damage

Damage I would normally be taking before damage reductions: 100

Mitigation math:
100 - (100 * 0.40) = 60
60 - (60 * 0.60) = 24
24 - (24 * 0.08) = 22.08

Damage I would be taking after damage reductions: 22.08

Is this correct?
Yes.

A shorter way to write it is like this:
(1-.40) * (1-.60) * (1-.08) = .2208

That makes it more apparent that the order of multiplication doesn't matter.
i would be interested in finding out where the meta gem magic damage reduction gem fits in as well as the 6% from blade barrier.

EDIT: basically looking for an equation for pvp physical damage reduction and pvp magic damage reduction
Just tack on the multipliers.

Complete DK physical:
(1 - resilience) * (1 - armor) * (1 - .06) * (1 - .08) * (1 - .10)
All of the inputs should be proportions, not %'s.

.06 is Blade Barrier
.08 is Blood Presence
.10 is Scarlet Fever

Magical:
(1 - resilience) * (1 - .06) * (1 - .08) * (1 - meta)

Resistances follow their own probability formula, but since it's a multiplier, the order in which it's applied is irrelevant. You would have to do a die roll to figure out what % resist you can get, but you could just multiply the above by (1 - average_resist). In a large sample, that's what it would come out to.

Yes.

But armor is for physical damage reduction and a lot of attacks are have 2 components (physical&magical), or you're versus a caster so it's worth noting:

(1-.40)*(1-.08) = 0.552 for spells

Conceptually, you're correct, but you left out Blade Barrier. You would multiply the corresponding portions by their corresponding reductions (physical with physical, magical with magical). See my other post for the formulas on both.
