It is because the AI has INSTANT PIP management. This is well beyond natural human capabilities. If it is shooting at you, it has INSTANT MAX PIPS to weapons, if it is turning away to run, INSTANT MAX PIP engines. It most likely can instant max PIP systems for every single individual round you fire at while switching between SYS and WEP max.
I like ENJOYABLE challenges that allow you to use varying methods to succeed, not cheap poor programming cheese "challenge" that pretty much allows the AI to exploit well beyond average human capabilities and sticks you into a single repetitive pattern/build to win. Reminds me of various fighting games where you have all these moves available but end up using only one surefire combo pattern because its the only one that works on the AI. Computer chess anyone?
Lower ranked AI doesnt even do ANY pip management AT ALL, never mind 'godlike perfect instant'. And pip management has nothing to do with power management, JManis even gave you a video to explain it. As Jesus said: lol.
I have the feeling if you were to fight other cmdrs you wouldn't do that well either...
