I've encountered that issue as well (the accuracy being reset to 200 thing). Looks like it's a bug if I'm not the only one getting it...
I just got finished my tests. This is what I've noticed.
- AI has a delayed reaction time before it actually aims and fires. This also happens with my beam fighters.
- AI will not use the full firing rate of any stock or CC cannons.
- If your weapon has multiple outputs, the AI will not use focused, unfocused or volley fire. Instead, it will fire every output sequentially in a burst, pause for a second and then repeat.
This is especially disappointing since I built a 4 output CIWS-type turret that has a firing rate of 2400 rounds per minute when set to volley fire (that's 40 shots in a second) at 47 damage per round. Something like that would be an ideal small scale point defense unit but the AI limits me to about 240 rounds per minute via a 4 round burst every second.
