What I'm saying is that, to a certain extent the accuracy of the FM's is irrelevant.

The DCS P51 (until the 190 comes out)and Accusim aircraft in FSX can be as brilliant as you like and the developers can wax lyrical about the accuracy of the depiction, simmers can rave about this feature and that. However it isn't until you compare one aircraft to another, head to head, that the true accuracy of the depiction becomes clear.

For example, you might have a developer put out an aircraft that they claim is within plus or minus 10% of the performance of the actual aircraft. In other words it's 90% or more correct. That sounds impressive, and everyone may be thrilled with the aircraft and how it behaves (I know, I exaggerate, you can't please everyone all of the time, that would be foolish). Let's call this aircraft(a), unfortunately instead of having a top speed of 360 mph it can only fly at 330 mph, a deficit of about 8%, within the developers margin of error. This state of affairs presents no problems and everyone enjoys the feeling of flight, sounds, visuals, indeed the whole package is a roaring success. However the developers, a few months later, come out with aircraft(b), it also has the same high fidelity flight model and the package is produced to the same standard as the former. However aircraft(b) just happens to be 10% faster than it should, flying at 330 mph instead of 300, still within the developers 90% accuracy claim, but faster, none the less. Aircraft (a) and (b) are arch rivals and matched up very well, each with their own strengths and weaknesses. Aircraft(a)'s only real strength however lay in the fact that it was faster than aircraft(b), that in every other respect, beat it hands down. Neither aircraft is significantly wrong and both lie within the developers claims of 90% accuracy however aircraft(a) now has no historical strengths and cannot compete in a manner that might have been the norm during the events depicted.
Of course if both aircraft were out by the same margin, in the same direction then, despite arguments as to the real figures, both aircraft could still play to their historical strengths.

Obviously the figures and percentages given here are purely notional, and exaggerated, but never the less, even with claims of high fidelity FM accuracy(90% or more, they can be seen to very quickly distort the whole historical balance of the events trying to be depicted.

This was unfortunately, possibly because of the limited source data for the developers to work with, a real bone of contention in RoF and the tinder for many an argument within the community.

It is all well and good producing a brilliant depiction of an aircraft in it's own right, but if how it fits into a wider canvas, such as a combat flight sim, is ignored then it will inevitably shine that little less brilliantly.
