Well.... kiss my grits! Normalizing the Kill/Death of each fighter vs all other vehicles (as close as I can easily get to each fighter vs every other fighter with the score data on the web site) nets some pretty surprising numbers if you simply normalize and range them to get an ENY value between 5 and 40.

The biggest surprise for me was where the F4U-1 would fall in a purely mathematical ranking based on K/D. I can't do anything but die in her.
Whoops, here's the ENY Table with the ENY in the proper direction, and with the last few characters of the aircraft name intact so that you can tell which Hurri is which....
