Ok, looks like we could do this forever. Thread started with doubts in proper P-51D modeling, which was cleared, it seems. And then, after replying to 19:1 kill ratio, I was drawn into the type of discussion I dislike, away from pure plane performance and numbers.
Here's my last try:
To me, Luftwaffe had great individuals. Pilots who started from glider training in 30s (some said it was the best E training they could get), gathered experience in Spain, developed new tactics and formations, then fought for almost 5 years of in just about every European front. They flew mostly 1 plane type, not an unimportant factor. Real aces, with scores way beyond 100 and 200, some even 300. And their kills were never like Allied "decimal" scores etc. Sure the best scorers fought on Eastern front, but some of these individuals shot significant number of Western flown aircraft. And now you say there comes P-51B, outnumbered, and shoots down most of those aces in 2 months period of 1944, just to leave Luftwaffe with newbies only ? Remarkable achievement, but I can hardly believe it.
P-51B was better in many important aspects than LW planes of the time: speed, dive and range. I'll leave guns discussion to someone else, and turn performance was not that important, IMO.
Pilot experience ? How could anyone know who shot who ? And even best pilots can lose against newbies if put in bad situation. Who was an ace there, and who was a newbie, we can never know.
But I won't argue anymore, since there were many other factors than plane performance and pilot experience. Mission objectives, elements of surprise, intial advantage, formation setups, plane condition, supplies...most of these come to mind.
But I would like to go back to the subject of this thread.
I consider P-51D the best streak machine in AH. Just like it was in real life. Also, 190A-8 is no match for P-51D IMO. 109G-10 can give it a run for its money, and rightly so. Still when I fly 109G-10, I consider P-51D the most dangerous opponent, besides other 109G-10.
Quantity or pilot experience can't be modeled, and luckily late war reliability or fuel quality on LW side is not modeled.
So, I will stick to flying now (after I get new pots

). And yes, I like to shoot down P-51s, even more after this thread.
