You list the top speed of the 109G10 as 328/356 (i believe, i check last night) at 100 feet- according to HTC it goes faster than this. Your data also has the LA7 going faster than what HTC has on their speed charts at 100 feet.
Lots of possible reasons for differences. Fuel load, ammo load, etc. For example, on the 109G-10, the speeds were recorded with a full fuel load and 0 usage. Tanks were full the whold time. In general, I tried to test all planes at a similar
duration of around 28 minutes rather than a similar percentage. In all cases except scramble time, use rate was set to 0.001 so fuel states remained constant. You can read the exact conditions and procedures for each test, and reproduce any you doubt!
If you come up with different results, let me know and I will run that test again!
I have tried to reproduce HTC's results with the F4U and was unable to. Even with no ammo and almost 0 fuel, I could not reach the speeds their charts indicate. Not sure why, but I am confident in my methods. (Background, I just finished duty with U.S. Army Test and Evaluation Command, where I designed evaluations of equipment the Army was considering buying). Biggest concern is my sample size of one test for each area. If I blew the reading, it got recorded.
Biggest thing to remember is that rarely will you encounter a plane in the arena under the exact same conditions I tested them at. It makes a difference. Like I said, feel free to reproduce any questionable tests and, if you get different results from me, I'll run them again here.
