Because I don't fly a fighter into CV ack as a rule, I always keep track of what does shoot me down when I fly around in it. Eight times out of 10 it's a player in a 5inch that gets me. The other times when AI gets me, a dead pilot or set on fire.
I agree bombers seem to lumber through the AI ack unaffected. I see shot down with player 5inch or shoot down with my 5inch position more bombers than I've observed the AI knock down. So is the AI ack in fact very tame and we have very player friendly 5inch gunnery?
You can test the AI ack by locating an enemy CV and fly straight and level over it a few times in fighters and bombers at about 10,000 ft. Keep track of your damage for those who say bombers soak up more damage. Aside from a pilot kill or engine on fire, bombers are impervious all the way to the IP point which is what kills the CV. Then tally up what killed you when you do get killed and the damage for each flight. 2.5k yds and closer we all know the ack will track you easier and player 5inch won't miss very often.
