The problem with the Excalibur's auto tracking guns however is that they are tracking on the center of mass of your target. While this is just fine for fighters, it's useless on capital ships if you want to take out turrets. I always turned it off so I could have more precision gunnery.
I'm not sure if the versions were different, but on nightmare, even when aiming, the ship often exploded only a shot or two after the turret. Maybe this is because my shots from farther away are missing the turret and hitting the ship. Even so, when you get close enough to aim well at the turret (which requires you to fly in a straight line towards it), it's aiming well at you.
