Thanks for taking the time to look into it. I think the real issue is that the malfunction chance hurts way more on ships with fewer components. It would be way less painful if I had every mount filled, even if you kept the same frequency as in the video. The other issue is that the frequency is actually random, or so it seems. In the video I took, they are actually pretty evenly spread out, which doesn't usually happen. Sometimes you'll go a full minute or so without anything happening. Other times you'll have two or possibly three happening at the same time. Again, with only 4 weapons on a ship, it really hurts. In any case, halving the frequency will definitely make it more palatable.
Also, cool-running drive stabilizer is way too strong. Takes sensor profile into the negatives easily. I've never seen it come up naturally though, so I'm guessing this is something you're probably not supposed to have, as you actually have the Well/Poorly Insulated trait, but I figured I'd mention it just incase.
