Ship Combat Question

Hello when I was doing a Mission the Damage I was doing to the fleets was off even taking in account for Shield Accuracy and Defense.

Now I just want to know if I misunderstand the combat rules or if its a bug?

Here is a dunp of the ships stats.

I don't feel like doing all eight fights by hand thats why there are only four.

The real outcome of my attack is not the same as when I do it on paper.
I am miscalculating or is this a bug.

Also if the look at the real log below you will see that the fleet The Fearful Privateer MK 12 takes out some of my Fleet that has about 200mil Def and The Fearful Privateer MK 12 does about 80 mil after acounting for Acc, Def, and Asb
