No offense but style of play comes into play here sir. Furballing in the MA is not a choice a lot of folks make. I've watched and seen a lot of styles lately. Hovermonkeys, Altfairies, Fringepickers, 12 Clearers, Scoretards. Even if you choose to fight 50-50 one half being furball, you won't have scores that look like this. Dodger is as good as I've seen in the F6F and his scores are not close to this because he is about 90-10 furball.
Scoring vs fighting...any solid a/c can come up with those numbers or similar numbers depending on the pilot.
It isn't just style....
90% of MA pilots I encounter are not very skilled. Pretty easy to kill, assuming they stick around to fight. Among the other 10% are the skilled and a few genuinely talented. Furballing virtually guaranties you a poor result. That's fun if you don't mind unrealistic combat and simply enjoy the scrum. Sometimes I'll join the furball, but not commonly. I usually fight on defense, often against the mob.
To run up a great K/D, you usually need a very good fighter. Over tours 164 and 165, I managed 95 kills to 3 deaths flying the N1K2-J. Please understand that I do not fly any one type consistently. I have no favorites, but choose based upon the need and my mood at the time.
Dodger is a very good stick, and I've had fun fights with him many times. Unfortunately, I've caught him low and slow often. Redd is very good in the F6F, as is Greebo.
The P-47D-11 is a high altitude fighter. You seldom see one on the deck (unless he just dived from altitude). I would expect that the Jug would have more kills of the Hellcat than vice versa. The fact remains that if a P-47D-11 encounters a Co-E, Co-alt F6F-5 below 15k, the P-47 is at a clear disadvantage. At 20k or above, the Jug has the clear advantage. In between is largely a toss-up. The fact that the F6F-5 is modeled 20 mph slower at critical altitude than it should be, doesn't help.
