Could you implement the Wreckfields into the CR displays/summary? It would just need some calculations for the shipcosts, the other relevant data is given in the API.
Sorry to use your thread, but something that has also been in my mind. I think it could be also welcome if the theoretical profits where shown regardless of the real profits of the battle (which should be shown too). I think it's relevant for a battle to show what was the profit the attackers (or defenders on a ninja) aimed to, to contrast with the real end result.
