Better 99 rates of success

[Protoculture]

I have noticed when performing a 99 attack that occasionally I will be left with a few troops remaining while the defending castle also has troops remaining. Through my calculations I think are correct this can happen quite often. This presents a problem as that forces another round then the enemy has additional troops the next round and I lose. I am suggesting that instead make the calculator force another calculation using only the remaining troops omitting the fortifications for the second calculation. As if you keep the fortifications you will never win a second calculation. thank you

Example

2 spears 99crossbows and 2 Armored horseman defending a castle.
If I attack with 99 axeman(from a fort) that would leave about 18 axe survive and 1-2 spears. If you run the calculator again omitting fortifications I would win the castle. Keeping the fortifications I would lose. Wait for the next round and he added another 51+ troops and I lose. The point is you say both sides must have 100 troops or more for another round to take place but that is just not true in this scenario. Thank you
