[Warlock][Affliction]Agony formula

WoW Freakz spell link: Agony
Bug description: The last tick of Agony does more damage than it should.
Proof: The base formula from 5.4.1 is: (324+30.6%*SP)*10. This is actually the formula for Agony at 10 stacks. Agony has 12 ticks, so if we'd want to find the damage for 1 tick at 10 stacks: (27+2.55%*SP)*10.
So based on this test, the formula was determined using a video from patch 5.4, when Agony was buffed.

Published Sep 13, 2013. This was under 5.4.0 (Mon Sep 09 2013) Build 17299. The formula then was (384+36%SP). Per tick meant (32+3%SP).

He has 38214 SP (23261 from int + 11479 wep) and DI buff. Using 5.4 formula, he would have done up to 25097 dmg (used 10 stacks, not 11).

Published on Feb 6, 2014. This was under 5.4.1 (Mon Oct 28 2013) Build 17498. The formula is the one we have today (27+2.55%SP).



Agony should work like this:
1. calculate the base damage for 1 stack using the formula (27+2.55%*SP)*multipliers.
2. the first tick does twice the damage.
3. each successive tick gets half of the first tick incremented
4. tick10, doesn't get the increment.

So if T is the base damage for 1 stack of Agony, we'd have: 2T 3T 4T 5T 6T 7T 8T 9T 10T 10T 10T 10T (12 ticks).


Proof:
SimCraft:


183 SP and 24.8% mastery.
Math: (27+2.55%*183)*1.248 = 39.5 dmg for 1 stack of Agony.
tick1: 39.5*2 = 79
tick2: 79+79/2 = 118.5
tick3: 118.5+79/2 = 158
...
tick9: 355.5+79/2 = 395
tick10: 39.5*10 = 395 (or the same formula as tick9)
tick11: 39.5*10 = 395
tick12: 39.5*10 = 395

5.4.1 Video:


22836 SP and 55.17% mastery.
Math: (27+2.55%*22836)*1.5517 = 945.4 dmg for 1 stack of Agony.
tick1: 945.4*2 = 1890
tick2: 1890+1890/2 = 2836
...
tick10: 945.4*10 = 9454

WoD Agony test:


1040 SP and 24.8% mastery.
WoD formula for 1 tick: 3.6288%*SP
Math: 3.6288%*1040*1.248 = 47.09
tick1: 47.09*2 = 94.2
tick2: 94.2+94.2/2 = 141.3
...
tick10: 47.09*10 = 470
tick11: 47.09*10 = 470

Ok, the values aren't exactly like in the photo, maybe I didn't used the correct formula, but we're talking about how Agony stacks are applied. The way it is applied hasn't changed in WoD. In Legion they will change it.
If you look in the photo, you can see the first tick 97 dmg. Second is 146(97+97/2). Third is 194(146+97/2). Look at the last 4 ticks. They are all 483(48.3*10). The first of the four is tick9(tick8+tick1/2) and the last 3 are tick10, tick11 and tick12.(base dmg*10)

Discuss with proper proof, not what you believe it should be.

I will move this to confirmed, if someone has an counter argument send me a PM.
