I'm pretty sure every pilot that flew these birds was way more qualified than some non-pilot simulator pilots some 60 years later. I know its confusing reading all the conflicting pilot reports (I would kill for a ride in one of the new Fw-190's from Flugwerk, as this seems to be the most mythical aircraft in terms of performance). All these variables depend on aircraft loadout, fuel, altitude (ex. density altitude at the time and season, field altitude of where the testing took place etc.) , possible damage from capture, fuel type etc., translation errors, unfamiliarity with the aircraft etc. Wayy too many factors. I can take one thing away from the quotes you stated: The Fw-190 (BMW) is a heavier low altitude fighter, and the 109 is a smaller lighter high-altitude fighter (which we all knew anyways). If Oleg took every pilot report of every plane the planes in IL2 would be a mess because its all qualitative information. Official flight tests, factory documents and talking with real pilots is the only way to get accurate information. I know your being facetious, but I would be careful about saying that these fellows were idiots
. They were the real deal, and they get my respect.
