Oh, dear.
On a flip side, are there some good graphs or datasheets around from properly adjusted 190's?
I mean, when it comes to i.e. the Spitfire, I have a lot of data on many variants of many models, - when it comes to 109's it goes more scarce (particularly looking for 109E's) and on the 190 very little.
So, to keep comparisons civilized, maybe look at the figures of real 190's vs the same models that the allied tested? If there are any.
