Okay, I stand corrected on the atmospheric temperature but it also says the top speed was 431mph... should we dwell on that now as well? Besides you already dismissed the data in question when you made the little red arrows pointing to the fact that the aircraft used in that test was "the cleaned up version". And as I have pointed out twice since then:
This test was done early in 1943 on the earlier 1942 F4U-1s. After which the improvements were made and the C and D models were produced. Once again, refer to
THIS document for the relevant test results on the 1944, 1945 C and D models we use in the sim.
What I want to know is why are you trying to nit-pick at every little thing you can find simply to dismiss the facts when YOU KNOW the F4U in the game have nowhere near the capability they should. The real world data is in front of you, please just fix the mistake.
