Cut the crap gripen. These specifications are the official figures for the aircraft, and the manufacturer guaranteed performance to be within 3% of that. It's just plain obvious that you got nerveus that the much hated 109 would get fixed and throw in the 'it's only calculated' BS.
"If you look same set of papers as that GL/C-E data you can find well over 700 km/h claims (with the DB 605A) for the Bf 109G by Mtt."
Show those papers if those exists. I've seen one paper claiming 700kph, and it's very clear about the nature of the curve. It was prepeared by Rechlin, not Mtt, and contains simply estimation of the 109G speed calculated from the 109F with the 605A output. The figure isn't unbeliavable at all, considering it's probably not corrected for compressibility and assumes wheel well doors that were foreseen but did not made into the production Gustav, except a few examples. You made a false story out of that on purpose, 'revealing' da great mtt conspiracy to dismiss the official figures. In any case, 700km/h plus speeds would not be anything extraordinary at altitudes considering the GM-1 booster in some of the 109G. With that, the 605A put out about as much power as the RR Griffon, oh, and btw, we have the Spit XIV in the game that is just the like isn't based on any real life flight test results, 'just' calculations.
Your dishonesty is bothering. You have the G-5/AS speed results yourself. You can compare them to those bad bad calculated figures by Mtt for the same plane, and find how closely their calculations match the actual flight data. You probably already did, just playing your usual distgusting games here.
