Some points:
1- Why would Oleg, (or anyone else), program in wrong rollrate data, if he had hard test numbers right in front of him?
2- Why would Oleg discount the accuracy of NACA data?
3- Is it possible Oleg is misreading the data?
4- Is the data wrong?
My core says go with #4. Since Oleg is OBVIOUSLY saying NACA tests are in error, then I guess it comes down to "EACH HIS OWN", as far as which flight data you choose to believe.
For the past 60 years, the common knowledge was that the Fw190 was a FEROCIOUS roller, and the Bf109 was heavy at higher speeds.
Suddenly, a man designing a *computer game*, comes forward and rewrites 60 years of historical belief?
I know that sets myself up for other arguments like "the world was always flat until one man..."
But WHERE O WHERE were all the Luftwaffe pilots at when books and documentaires were ALL SAYING THE SAME DAMN THING?
Did the History Channel EVER hear one of their interviewees say, "hm.. you know, the Bf109 was a much better rolling aircraft than the Fw190..."
And why are some people so inclined to believe Russian data which has so suddenly come to light within the past 2 or 3 weeks in our world?
Think about it, this "new data" has just come to light, Hell 3 weeks ago, I never knew of anything about Russian data putting a faster rollrate on the Bf109.
So before anyone jumps aboard the Russan bandwagon, I would stop and consider that this is new data of which hardly any of us has seen. Until Oleg posts some of his sources, and even then, we still have to question it's reliability.
Think about, Oleg is about to repute 60 years of common knowledge with the posting of some russian documents... This evidence will dispute all the documentaries and facts that the aviation community has come to embrace.
Imagine all the museums across the world that will have to change their descriptions that sit with their Bf109's and Fw190's...
Imagine all the documentaries that will have to overdub their narration.
We are all about to witness an historical event.
Just think, 50 years from now, new Russian data will put the Mig25 Foxbat at mach 4.5
