There are several ways to calculate battles:
Number of each unit in your fleet against that of your oppenents fleet, this only works early on against specific opponents.
The normal method should be used most of the time. power of fleet= (unit basic power x number of that type) repeat this for each unit in your/the opposing fleet armour of fleet=(unit basic armour x number of that type) repeat this for each unit in your/the opposing fleet
This is still not as accurate as it could be but it makes do for small conflicts/occupations.
This is more work. It is done for larger battles where more different types of units are concerned. By calculating what happens before the battle takes place, you can optimize your fleet to improve the ratio's.
power of fleet= (number of unit X basic power X (1+power modifier from tech/100*)-shield X (1+shield modifier from tech/100**) defence of fleet= (number of unit X basic armour X (1+armour modifier from tech/100*) This takes into account the whole shield value of the opponents fleet thus the total damage is much lower than than the theoretical damage before shields.
where the modifier is +55% the calculation is 1+(55/100)
oppenents shield tech levels
