It's impossible for you to hit a plane maneuvering 10 seconds down-range at 400mph, perpendicular to the 5" pov. Unless you're guessing where the plane is going to maneuver in the next 10 sec and win the lottery.
It would appear that the Puffy ack code doesn't take into account angles like you describe but only the random chance of getting hit if you are in range above 3k...
It wouldn't hurt to go back to the drawing board and see if there's a more effective, more realistic way to design a system to better address a lot of problems people have been reporting such as: fighters being more frequently affected (killed) by the puffy ack than bombers, impossible angles (through mountains, perpendicular shots), absurd accuracies at 20 mile distances, absurd accuracies at 400mph+ fighters.
Perhaps 'the box' that has been mentioned by HiTech could be enlarged to a greater degree as the speed of the airplane increases? HiTech, you have said that a fast airplane does have a larger box, but perhaps the box is not getting as large as it needs to as the speed increases?
