You will have to trust me on this, the AI does not cheat in tactical combat.
I had quite a number of situations where I would take all of the weapons on the ship without taking any other components in the process. But I do remember that feeling when I play some game that uses random number generator (like RISK) for a long time. After a while I would get the feeling that random number are not so random. It is not real. Just like you said, you are looking only at the bad points.
Also, there is one more thing. Larger than normal weapons mounts have greater damage resistance and may go down Last.
