and you know that the sims are using the 2001 data? try again, the redesign was 2005 and I'm sure they ran the numbers and entered the right data, as was said its the 9 top air forces in the world that are running the sims, it's not LM locked in a cupboard making up numbers
but think what you want, you may even think how fast, high it goes the better with a WW1 plane vs plane dogfight mentality
The sims are conservative which is why you get better numbers when it is piloted
