We give it 8 and it should be 4....... THAT is an issue not 8 should be 7

So, can we settle for a rule of thumb that you are interested only in aircraft speed errors that are at least +2 from the "correct" value? Because if we assume that speed at sea level is typically -1 from top speed at altitude like you suggest above, there are a lot of those errors still in the current OOB. When I went through the USMC aircraft, quite a few them had speeds +1 higher than they are supposed to have according to the Mobhack guide rule, and most of the real max. speeds were attained well above 10,000 feet.
