formula for unit stats

[scsscsfanfan]

I guys, I used to play war games so I'd like to calculate the odds.
I woulder that if is there a formula that calculates the chance to kill on an engagement?
I mean, eg, gallowglass has melee bonus 5, defence 0, armour 2 and feudalsergeants has Melee 0, def -1 armour 1, then is there a formula something like "chance to kill = Mel-(Defence x armmour)": 5-[(-1)x1]=6, therefore at 1 to 1 encounter the feudalsergeant is 6x morelikely to get killed by a gallowglass?

And aslo, for units that have cavlry att/def bouns, is the number added to the melee/def value when against cavlry?

Or in the end, dose all these matters at all?

Know where to find all the kill chance %?

Wish I could post it all for you but I would be here all night typing that chapter in the book. http://www.totalwar.org/forum/non-cgi/emoticons/eek.gif

chance to kill = 0.019 x 1.2 ^ (melee - defense)

(melee - defense) is limited to the range -20 to +20.

anti-cav bonus for spearman is +1 melee and +4 defense
anti-cav bonus for pikeman is +2 melee and +6 defense
anti-cav bonus for polearm is +3 melee and +1 defense
armor piercing bonus to melee is (target armor - 2)/2

There are also shield, flanking, height, fatigue, formation, routing, charging, pushback, supporting ranks, camel vs horse and sword vs spear combat bonuses. Each man can strike once at an opponent in a combat animation cycle, but may have to defend more than once in that same cycle.
