Is battle basically (power vs structure) * rounds?

Ok guys, sorry if it's a n00b question, but I couldn't find the answer.

From my few battle reports, it looks like the battle engine subtracts from your opponent the damage you cause from his structure, round after round, until there are no more rounds? And then, if their structure is zero and your structure is greater than zero, then you won? Is that how it works?

So, for example, 1 scout (structure 4000, power 350) vs 1 cargoship (structure 4000, power 1), the scout will always win but will require 4000/350=12 rounds to win? If the attacker (scout) selects only 10 rounds, it will be a draw?

Thanks! I'm just not sure how the battle system works!

The battle is won, when one of the players is left without any ships/defences on his planet. In your example the scout will only win if the battle is in 12 rounds, otherwise it will be a draw - both of the players have some ships remaining.
