Damage = (8.8125 + Might/8 + 2.5*DAM + Weapon*Ingress)*Fury*Invisible
To add a few things which may be of use.
The above formula does not work precisely for all Might and Grace ranges, just all the ones that are usually of any concern.
The Might range it is restricted to is values north of about 72.
Grace isn't in the formula, and doesn't seem to matter, if Grace is north of about 100.
I was able to get the terms so precise by testing with my wife's Rogue when she turned 99. She started out with a Grace of around 100 and a low Might. She then purchased Might point-by-point and we recorded the strike results. That is one of the reasons Grace does not appear.
When testing with a new 99 Warrior, whose Grace and Might numbers are reversed, you will notice a loss of about 6 points of damage. (From the Grace of 40 or so versus 100)
Grace isn't in the formula, however, because we have never been able to lower it from 130 enough with Corrupted rings and such to "break" the formula as written.
The Weapon*Ingress term is probably more properly expressed as (Weapon/2)*Ingress, where Weapon is a value in the range of X to Y from the S:XmY of the weapon.
The reason for this is because the formula is, as you stated, for AC 0. However, I believe, the appraised damage values for the weapons are for AC 100. (Which makes just as much sense, since a level 0 character would have a 100 AC. That way the ranges have a very close relationship with the actual damage done by new characters.)
The Polearm Factor appears to belong on the "outside" with the Fury and Invisibility multipliers. Brief testing from late 2003, shortly after the Polearms came into being, showed it to vary from Polearm to Polearm. The results observed at that time were:
Polearm: 2x,
Heavy Polearm: 2.3x, and
Military Polearm: 2.5x.
The formula used to be very accurate. (Occassionally off by 1 point due to rounding or such.) Whether any of the constants have changed or not since I last tested it extensively in 2003, I can not say for sure.
I did retest Invisible just the other night with my wife, and it was doing a 9x damage multiple. In the past I have seen it do an 8x. So, nothing is written in stone, or wasn't anyway. They used to tweak things occassionally. I still remember when we used to get a 1.5x bonus for striking a Flank. Now it is just 2x for striking the Rear.
