Like I said before, your test does not adequately represent what is typical in an event, FSO or otherwise.
Rarely are single bombers ever used by players, but when they are they die just as easily if found unescorte. But it's foolish to grade the effectiveness of the AI when the result is the same as a bad player plan gone poorly.
BTW those "Brain-dead bozos" shoot better than most players from the looks of it.
