Hey, don't make this into a 190 thread, 190 dweeb
Anyway, do you have the performance of the XII at hand?
I remember a tale of Harris. He had 190's jump his squad on purpose, countering with a high break. The 190's could not outzoom that one and had to run, but he could catch them.
Basically, after losing the initiative, the 190's couldn't do anything the XII couldn't.
But in 1941/42, 190 vs normal Spit V's, and perhaps even some Mk II's, now that was the reverse story.
Supermarine was still hairing out the roll rate quirks, and there enters the 190, fast, heavily armed, uber-rolling, and AGGRESSIVE! So, the 190 was the devil in the sky, for a good while.
Oh, speaking of MTO recognition of the Spitfire, there are some things to bear in mind.
1. The IX and V look almost identical, - in the air the difference cannot be seen.
2. The VIII adds a bit to the confusion.
3. There were many mods around. V's with modded exhaust stumps, clipped, chopped, chopped, etc.
So a Spit was not just a Spit if you see what I mean.
But the bulk of the early desert war was the Mk V with the Vokes filter which really created a lot of parasite drag. At times, those got outrun by Ju88's, and they were outperformed by both the 109F and the 190.
A tactical move by one of the RAF commanders was to "stack" his squadron rather than staying at a certain altitude. The top guys provided cover for the others, and it worked quite well.
Anyway, gotta rush. Will bring some stuff into here later on.
