With a stack of 5, the DoT is 50 DPS base with a DPS spellpower coefficient of 0.05733. The extra damage proc is 20 PPM and hits for 7% of your spell power, which adds 0.02333 to the coefficient. That's a total coefficient of 0.08066 vs. SoRs coefficient of 0.092. You would need over 2000 spell power for SoR to overtake SoV. You similarly need 1200 spell power for JoR to overtake JoV.

Assuming 500 spellpower, a 1.8 speed weapon, 10% melee miss/dodge/parry, and 10% resist rate, SoR does 65.25 DPS. The SoV DoT does 78.665 DPS. To lose the stack of 5, you need to not proc the DoT 8 times in a row. The chance of proccing it is (0.6)(0.9)(0.9), or 0.486. The chance of NOT proccing it is therefore 0.514, and the chance of not proccing it 8 consecutive times is 0.514^8, or 0.004872. That's a less than 0.5% chance to lose the stack. On top of the DoT, the instant proc adds 5.67 DPS, for a total of 84.335 DPS. It's MUCH higher than SoR. At the same time, JoV is doing 101.875 DPS, while JoR does 72.375 DPS. These two seals aren't even close, SoV is better even if you assume the 5-stack is only active 80% of the time.
In the nicest way possible, your math is wrong. Sorry. At about 900 +damage (including JotC, why do people -always- forget the 219 from that? Or the damage from oils/improved spirit?), SoR pulls way ahead because of the judgement coefficent being, well, high. Don't forget that the judgement and application resist seperately.

And for those who think I'm crazy, here's some math:

SoV:
wpnSpeed= weapon speed
bAvoid = Boss Parry + Boss Dodge + Player Miss
dam = +damage
time = Fight Length
spHit = Spell Hit %
sStack = Avg. swings till full stack
bProc = Base proc rate (assumes 20 PPM)
procC = Actual proc rate
pFall= probability (per swing) for stack to fall

bProc= 20 * (wpnSpeed/60)

procC = (1-bAvoid)(max(0, 0.17- spHit))(bProc)

sStack = 5/procC

pFall = (1-procC)^(mod(15/wpnSpeed))

Probability that it will fall off at least once:
(1-pFall)^(mod((time-sStack)/wpnSpeed)

Average number of times it will fall off:
pFall(mod((time-sStack)/wpnSpeed)


Plug in the numbers, and get the chance it'll drop off and how long it takes to build up. For me personally I have a 0.000027 or so chance to not have SoR beat SoV on a fight like VR. Yeah, let's get right on that.

This math could be horribly wrong. I'm frankly not that good at anything to do with nontrivial math. If anyone sees an error -please- let me know.

Honestly my hatred of SoV has climbed to new levels on Illidan, where I can with 7 expertise stand directly behind him and -still have a whole stack fall off continiously-. !@$@!$@!$@! On PoJ, though, I'm curious where you find points for it. I wouldn't dream of really tanking with this current spec (heroics don't count) and really wish I could fit another half dozen points into my spec. Or that we raided with a retadin so I could not take imp JotC.
