AIM-4F does not perform on the level that it’s stats card says it can. 15G limit on the AIM-4F compared to the 27G limit on the AIM-4G according to StatShark - See All Player, Missile, and Vehicle Statistics
It is allowed to pull 27G but that doesn’t mean it can actually pull that much, iirc it can only pull that much if it is at like Mach 3 or smth.
Statcard stats are known to not be accurate. They often use idealized numbers which are not reflected in game. (Also sometimes they are just not based on anything applicable to the game, like how for ARHs their range performance is based on IRL claims, despite most of the claims they’re basing them on often just tracing back to wikipedia).
