Unhelpful Revisionism
Kill-loss ratios say nothing about the quality of shooting. What they may indicate is that the British were not as well-armed as the Germans comparing eight-gun rifle-calibre weapons against cannon) or that the RAF used poor tactics (tight vic formations against the German finger four) or that the Luftwaffe often held the height advantage in a fight.
The truth is that the average pilot of *every* nation throughout the war would have had trouble hitting a barn if they were inside it. Aerial shooting, and particularly deflection shooting, was a difficult art to master. As a consequence most of the air combat killing in WW2 was done by a small handful of pilots.
Though there may be criticism of the quality of RAF training, no-one in any air force really had an effective means of training good shooters.
