Gun convergence was set to 400 meters. Very typical for US fighters of the time. Quite possibly back then they knew a gun works beyond point blank range.
If you can manage a fifty meter radius around an F6F sized target, conservatively assuming linear distribution, one in 800 rounds will hit the F6F.
Statistically, 8 hits require 6400 rounds. Ten mission with eight enemy aircraft, every aircraft needs to fire exactly 80 rounds to achieve that outcome.
The ground tests from the worst mount gave a ten meter radius, the best mount gave a two meter radius at about that distance. That leaves room for somewhere between 40 and 48 meters of aiming error. That's like missing a disc 3 feet wide from 20 feet away.
Just as a ballpark.
As to the "regardless of speed or angle, you will be hit, period" - I shot down eight of them one flight without being hit at all, and I did it from close range. Period. It's called "proper tactics", and it works better than whining.
