Point is, that the 190A series had plenty of combat with aircraft that had better altitude performance, beginning with the Spit IX.
That's not the point and never was. I have quoted you the line of discussion.
Even what you typed out above is nonsense. The 190A altitude performance was perfect for the altitude that combat was taking place at at the time it was introduced. In fact with the LF.MK IXs the Spits FTH was brought down to better compete with the 190A.
The search for better altitude performance with the 190A was being looked at since '42 but with little urgency. This had little to do with Spitfires and wasn't a major issue until the bomber campaign and high flying long range escorts were regularly flying over the Reich (read as P-51).
With the 190 they were looking at 3 different engines configurations to improve altitude performance:
B - BMW-801 w./ GM-1
C - DB-603A
D - Jumo 213A
GM1 was problematic and it was only really used around 2k meters above FTH.
The DB603 was preferred by KT but there were problems with the engine (the weight with SC was less then ideal for a fighter). Also, there were aircraft were slated to use Db603s and production of this engine was far behind meeting demand.
What was left was the Jumo. Ultimately, it was an improvement over the BMW but it didn't a deliver a much better FTH.
The Dora was a stop gap solution. It had the best engine at the time coupled to a 190 airframe to get something better to the front line. It had little to do with Spit XIVs or Tempests.
LW bomber killers were at the mercy of high flying, free ranging allied escorts (read as P-51). As pointed out above this is what ultimately lead to the Ta-152Hs.
But the above has F'all to do with my original post.

On the flip side the Spit XIV and Tempest got into the game before the 190 D9 which was in essence the counterpart to those fighters along with the P51.
and my reply was:
The 190D-9 development had little to do with the Spit XIV or Tempest. It was developed in an attempt give the FW series better performance at altitude. D-9s were most often used to escort the bomber killers. They were to deal with the P-51s. As it turned out the D-9s FTH wasn't much better then the A series. Ultimately, the need for a high alt fighter lead to the Ta-152H series. Like the 109s and the D-9s, the Ta-152 was meant to combat escort fighters giving the bomber killers space to attack bombers.
I don't think you are a troll but if you can't follow the logical line of discussion and stick to it then you are far worse off then I already think. Which is most likely the case seeing how you have done this type of thing in many other threads.
Stick to the topic at hand, don't build strawmen and make stuff up if you can't come up with anything to say.
