Again, someone asked for it, and I was curious myself what this would look like. The following is what I believe to be the best DPS possible on a standard fight for Disc, while also attempting to boost HPS as much as possible in the process.
NOTE: I am not suggesting this build to anyone. This is more of a theoretical look than a practical one.
Assuming:
(1) 5stack Evangelism
(2) 22% HST raid buffed
(3) 15% CRIT raid buffed
(4) 9000SP
(5) Eschewing MST
(6) The following spec: http://wowtal.com/#k=1ACd7U90.aei.priest.-4sHfw
Note: The 1/2 in RS is a throwaway point. Put it where ever you want.
2/2 Imp SW:P can be switched for 2/2 VS. It is a slight DPS decrease for a big gain in sustainability.
The following is a sustainable, repeatable rotation. Obviously it is not optimal because Blizzard did not intend Disc to be played in this fashion:
NOTE: I intended for the below chart to be expanded, showing how the timers work in sync, but it is too difficult to format on this forum. I'll try to do a .jpg of an excel spreadsheet later.
[TIMER][STARTCAST]
[00.00] PW:S
[01.23] SW:P(BT)
[02.31] DP(BT)
[03.39] Penance(BT)
[04.83] Holy Fire(BT)
[05.94] Smite(20%) [5.94]
[07.58] Smite(20%)

As can be seen, this rotation can be repeated indefinitely, never letting SW:P or DP drop and always having them affected by BT. Given the assumptions made above, the DPS breaks down as follows for the above chart:
SMITE:
([(BD*#NC)+(COEF*#NC)SP][TS*5xEVA])]+([(BD*#GC)+(COEF*#GC)*SP][TS*5xEVA*GoS])
([(692*4)+(.758*4)9000][1.06*1.2])]+([(692*8)+(.758*8)9000][1.06*1.2*1.2])
([(2768+27388)(1.272)]+[(5536+54576)(1.5264)])
(38358+91754)
130112
PENANCE
([BD*#C]+[(COEF*#C)SP])(TD*5xEVA)
([2232*4]+[(1.473*4)9000])(1.06*1.2)
(8928+53028)(1.272)
78808
SHADOW WORD: PAIN
([BD*#T]+[(COEF*#T)SP])(TD*TF*ISW:P*GoSW:P)
([221*16.22])+[(.185*16.22)9000])(1.06*1.02*1.06*1.1)
(3585+27006)(1.26)
34027
DEVOURING PLAGUE
([BD*#T]+[(COEF*#T)SP])(TD*TF)
([155*16.74])+[(.185*16.74)9000])(1.06*1.02)
(2595+27872)(1.0812)
32941
HOLY FIRE
([(BD+BDHoT)*#C]+[(COEF+COEFHoT)*#C]SP)(TD*5xEVA)
([1380*2]+[(.776*2)9000])(1.06*1.2)
(2760+13968)(1.272)
21278
===============================================
Given 15% CRIT over an extended period, this rotation and spec can output Approx. 9817k DPS and 6700HPS.
Add in 2/3PIs, Hero/BL/TW, and Shadowfiend, the numbers work to Approx. 10.7k DPS & 7.4HPS.
EDIT: I miscalculated the cast time of Holy Fire. The new numbers reflect the proper increase in both DPS & HPS.
