Computer coding. Turn up for buffs, down for fighters.
If I took the time to research I could find the velocity of the 5" from the Essex Class CV. We would do a simple computation and come up with the time it takes from discharge to hitting my bird in excess of 6k icon range, well beyond 6k. It would likely take in excess of 10 seconds for some of these magic hits on fighters. Let's settle on 6 seconds travel time. While that shell is in flight for 6 seconds, my Dora was traveling well over 450knts, dropping a couple thousand feet and, at that speed, moving almost 1 mile during that 6 secs. If the gunner had been tracking me at 15k alt, X range (6 secs of flight) traveling from East to West...puffy ack burst, 6 secs later I am at 12.5k, moving from West to East. Gunner was leading me further to the West, I'm now almost that much further but to the East...yet the puffy ack takes out one of my guns.
Point is, puffy ack should have little chance of hitting a rapidly moving, jinking plane. Fighter or bomber it is just not realistic. For a buff group at 15k making a 220knt straight line with no course or speed adjustments, they should get hit far more often then they are currently.
