I see you didn't completely understand me...
What I said was that knowing the rules means you can predict the results of one action, and understanding the reasoning behind each action.
Knowing all the rules does not mean that the game can be won using mathematic, there are so many randoms and possible counteraction the enemy can use, it is impossible to predict even the next few moves of a single battle, and certainly not an entire battle.
You should also consider how little information is revealed, you don't know how many units your enemy has and what kind of magic and magical items are available to him, all things to could extremely effect a battle.
Knowing all the rules simply gives you a quick and easy way to evaluate your army's strength with a few clicks, instead of having to gauge your power by standards which you acquire after many hours of playing.
Also, if you do inform us of all the rules, you'd better make sure there are plenty of randoms, because randomless rule WILL lead to calculator battles.
