Lazs is successful for a couple reasons. Lazs, this is no way an insult directed at you, so please don't take it that way- I know you are a very capable pilot.
Anyway, Lazs is successful for 2 reasons. First, he is a good pilot. That does play a role.
Second- Lazs doesn't fly alone. I don't believe I've ever seen him just out cruising around looking for solo enemies. He flies with his squadmates and they watch out for each other. Thus, he has more success in an "early war" F4U-1A than I think an equally skilled pilot who doesn't fly with a group of people would have. This, in my opinion, plays an even larger role in his success than his ability does.
I know it works that way for me, when I am flying alone I'll consider a 4 kill sortie to be a good sortie- when I used to fly with JG2 I wasn't happy unless I had 8-10 kills if we were flying as a group.. it is that much easier.
5 guys working together in inferior planes have a much better shot at killing 5 guys in superior planes that aren't working together than 1 guy in an inferior plane has at killing 1 guy in a superior plane.
