TITAN/SH TANK FORMULA:

I worked out the following point (CV) formula for the titans and SH
tanks in the Epic armies book. This formula will estimate all but two
of the titans/SH tanks within 15% and most within 10%.

Assumptions:
The Psyker ability is worth 10 pts.
The Tyranid ripper is worth 1.5 cc weapon.
The Ordinatus weapon is worth 9 "normal" SHW's.
2.5 power fields is the equivalent of 1 voltage field.
Dominatrix 4+ save is the equivalent of 9 PowerFields
Eldar 2+ save is the equivalent of 15 Powerfields
Armament is divided into weapons "slots" that take either a SHW, Cc or
FP type weapon - some titans then have many different "mods", but in all
cases a SHW is a SHW - the vortex missle on the Warlord is equivalent to
mega gargant Big lobba.
Formula:

CV = 11.1*[PShieldEq]+ 14.1*[Damage-4] + 4.6* [Assault] +Trans*10.6
+Cc*15.7 + SHW*15.6 + .36*FP + 102.1*SK + .6*spd + 112.5*(Arm-5) - 38.8
+ 10 [if a psyker].

where Shields is the power field equivalent
      Damage, Assault and Trans are the Army list values
      Cc is the number of Close Combat weapons mounted
      SHW is the number of SH Weapons mounted, regardless of type
      FP is the total fire power including that of any Cc weapons but
      excluding () values on SHW and the D3/D6 on the Eldar weps.
      Sk = 1 if skimmer, 0 if not
      Arm is armour value, note -5 so value is 0 if armour = 5.

Example:
Warhound: 2 void s, 4 dam, 12 aslt, sp 20, 12 fp, 6 armor, CV=200

= 2*2.5*11.1 + (4-4)*14.1 + 4.6*12 + 10.6*0 + 0*15.7 + 0*15.6 +
  .36*12 + 102.1*0 + .6*20 + 112.5*(6-5) - 38.8 = 200.72

Great Gargant: 6 +D6 pwr(use 9.5), 18 dam, 30 aslt, sp 15, 5 armor,
CV=430
Weapons: In my scheme the G. Gargant has 3 weapons configurations:
All have 2 SHW, Gaze of Gork & Belly Cannon, and 6 Shoulder FP plus
(1) Lifta Droppa and 8 FP battery for 0 Cc, 3 SHW, 14 FP
(2) Lifta Droppa and CC wep _at_4 fp for 1 Cc, 3 SHW, 10 FP
(3) CC wep _at_4 fp and 8 FP battery for 1 Cc, 2 SHW, 18 FP

The formula is for version (2) and is worst case of the three:
 
= 9.5*11.1 + (18-4)*14.1 + 4.6*30 + 10.6*0 + 1*15.7 + 3*15.6 +
  .36*10 + 102.1*0 + .6*15 + 112.5*(5-5) - 38.8 = 476.2

Formula gives for (1) a CV of 464 and (3) a CV of 465 respectively.

Problems(specific): The formula fails on the Battle Fortress predicting
a CV of 52 vs 85. No formula, and I evaluated many, came even close.
Statistically, the BF is not even in the sample population.

The formula significantly (20%) overestimates the Revenant titan at 221
CV vs its value of 185. This is due to counting each pulse laser as a
SHW vice a FP of 2xD3 (or 4). If this is substituted into the formula
it produces a more reasonable estimate of 191.

The formula underestimates the Dominatrix by 15%. This is because it
doesn't take into account the "Hive Mind" morale boost and Command
Function reroll, which would seem to be worth 73 points combined.

The formula ignores the vulnerability of SH tanks and Scout Titans to
Catastrophic Damage.

USE: As with any formula derived from a regression analysis, it should
not be used outside of the sample range, that is for armor less than 5,
for speeds less than 10 or more than 25 etc. The sample data array is
in an EXCEL spreadsheet which I will make available to those interested.
