Difficulty Calculating SoR Damage

I've looked everywhere for a good way to calculate SoR damage, but I can't seem to find a good formula.

I found this in the Threat Generation Sticky:

Good luck, this formula is a tough nut to crack. It is also affected slightly by weapon damage, and I haven't seen a formula for SoR that includes that in the calculation.

I posted some data on this, but never came to great conclusion. Here was my post:

if you check out the spreadsheet, one of the sections got shifted. Sorry about that, I need to go back and fix it.

0.85*(2610.43*MWS/100)+[0.03*(MW+mw)/2]+3.5+(0.094*MWS*SD)

MWS = weapon speed
MW = max weapon damage (from character sheet tooltip, not base weapon damage)
mw = minimum weapon damage (same deal as max weapon damage)
SD = spell damage

That's the formula I use for SoR damage/swing. It's still off SLIGHTLY but it should stay within 1 point of damage. One-handed spec is not included so you'll want to multiply that into the final result.

That's true, (MW-mw) is the same with or without AP being included. But you're missing out on somethin' there. I'm not talking about MW MINUS mw. I'm saying MW PLUS mw.

Just for reference and example, take my stats:

Base weapon: 19-129
My actual weapon damage: 80-195

Base:
MW+mw = 148
MW-mw = 110

Actual:
MW+mw = 275
MW-mw = 115

Different in both cases after AP and talents.

Jere, are you taking one-handed spec out of the equation? If you aren't, then you will get different numbers for MW-mw. But, by the same token, if you add one-handed spec to the equation for base weapon damage, then the numbers will be the same for MW-mw.

No, you shouldn't take one-handed spec out of the equation I posted above. SoR's damage does go up SLIGHTLY as weapon damage improves. But, I was just talking about the situation with MW-mw
