I hate the wrong data in Il2 strmovik 1946

What I think you're missing with regard to the modelling, are the aircraft relative performances. This has been modelled pretty well.

I might ask you at what difficulty settings and which map are you testing your planes. Crimea is the official test map, and I would think 100% setting would be the test reality.

Another point about 'reality' is that there is only data on paper to go by, plus a few relic aircraft. And then old veteran's comments, which invariably are biased.
So all-in-all, You now have the best combat prop-sim in your hands - period ( Most probably the the worlds best sim).

And of course you can always throw the disks in the bin - just make sure you don't empty the bin, coz you will be digging into the bin after a few weeks (of MSFSim, LockOn, other inferior products ).
