Gaston,
You can post cherry picked anecdotes all you want. You can misrepresent what has been stated by others all you want.
Your problem is that regardless of all of that, physics simply doesn't agree with you.
It is like you read an account of an Fw190 out turning a Spitfire Mk V and, ignorant of the specific situation in which that happened, locked onto all other claims, practical tests and so on that find that the Spitfire Mk V easily out turns the Fw190, all other things being equal as being false due to your first exposure being the contextless account of an Fw190 out turning a Spitfire Mk V when all other things were not equal.
And yet here we are, after 15 plus years, and still not a
single credible quote of the Spitfire ever out turning, at low sustained speeds, a FW-190A (but more quotes that the Spitfire
did out-turn it
around 280 knots and above, the exact contrary of what everyone assumes).
If a single quote demonstrated that, in speeds well below 250-300 mph, the Spitfire could maintain a circle with a FW-190A, but without burning speed from a higher angle of attack (to shoot momentarily "across the circle" at a smaller circle -which I only ever heard being done from
Spitfire pilots by the way-
all of them describing as being forced to do this: ie: Shooting with the wings rumbling to aim "across the circle"...), I would consider it a serious counter quote. Note I am
not even talking about
gaining... I am talking about just
maintaining the sight picture more than for a brief moment, in a turn that is not from a steep dive, basically.
Not one account has surfaced. And I have been looking for 20 plus years.
You keep mentioning specific situations, when most of the quotes I find are
general statements from the most qualified people.
Pierre Clostermann was the RAF's record mission holder at 400. He was, in addition, a trained engineer, and the only pilot I am aware of, on the Allied side, tasked with giving technical conferences on German aircrafts.
Do you think when he said, in these conferences, that the Spitfire could not out-turn the Me-109 or FW-190A below 280 knots, that he intended to get Allied pilots killed?
He said of the Spitfire's turn reputation (although the issue is not as much of a poor turn rate than of a poor turn radius) that below 280 knots this reputation was "a die hard legend"... Then you have, on the opposite side, innumerable correlations that the FW-190A
was a low-speed turn fighter, including a Russian overall conclusion (In "Red Fleet" Feb. '43) from one year of front-line combat: "The FW-190A will
inevitably offer turning combat at a minimum speed."
You keep talking about cherry picking, because you fail to see it is the overall picture that contradicts you. On the other hand,
you have US and British
Navy test pilots on your side!
The Spitfire Mk V out-turned the Spitfire Mk IX. That is just a fact you can ask any flying museum operating both of them today. Yes there is an odd Russian turn test time quote at 17 seconds (vs a more realistic 21 seconds for a Mk V), but then the Russians also removed the outer guns to try to get more maneuverability out of this fighter, which Galland called "great for aerobatics, but ridiculous as a fighter"... Yes, he was talking of the Spitfire.
Sure the Johnny Johnson quote is about
one encounter, but he CHOSE that encounter for a
post war article: Context is everything...
Johnny Johnson was not just the RAF's top Spitfire ace, he was also the top Western
FW-190A ace, with 20 kills
on FW-190As alone... Do you really think he would choose this particular combat for an article in 1946 if he thought it was
non-representative? This was not written the day of the action: It was
cherry picked, by
him, for a post war article... Johnny Johnson was the one doing the cherry picking. See how that changes the context? No, I guess you don't.
Consider the Clostermann quote: Do you think Clostermann, top French ace at 27 kills, and RAF mission record holder at 400, is more on
my side or more on
your side?

P.S. As to the physics you keep assuming are infallible, I can only point to the inability of a professor of physics to understand that, through internal leverages, an engineless car could be 2.8 times faster than the wind... He bet $10000 that this could not be the case, because, you know, internal leverages don't exist.
Same exact reasoning you apply here.
