Not a need as much as a style that I find useful and actually respectful in that I take the time to address each of your comments.

PS wrt my style, I have spoken with several mods and it does not break any forum rules!!

Really? Because I did not get that impression

Yes we have already established that you do not trust the math..

Got it!

So if not math.. Than what should we trust?

And how far off is it?

Only way to tell is to apply some math and derive a percent error

Agreed 100%

The part we don't agree on is the definition of reality..

I for one am all for checking against reality when reality exists.. Like real world test data

But when real world test data does not exist, than my point is you have to trust the math to fill in the blanks

Where as you want to fill in the blanks with anecdotical evidence..

And I have already given several examples of why that is a bad idea

You will never know if you will be below or above the mark. So I could as well trust in what we have now. I could as well trust in anecdotical evidence provided the sample is large enough to allow a statistically sound picture about the real thing. If 1000 pilots say the spit could outturn the 109 I'd tend to believe that 1000 pilots cannot be wrong even if I do not know the 1000 initial conditions.

If large enough?

Again, as I noted, EASY to say, but until you try you don't know just how hard it is to try and do that..

Many have made that claim over the my past 20 years of simming

All have failed!

All in all I would still take my chances with 6DOF math over some sort of statistical conclusion drawn from anecdotical evidence..

Why?

Because there is something you are forgetting about anecdotical evidence

We only hear from (read the reports of) the pilots that made it home to write about it..

Thus a filtered set of data!

In short, we don't know how many Spitfire pilots were SHOT DOWN trying to turn with a 109 and thus never got a chance to write about it!

Chances are it will not..

Again, not trying to bum you out

All I am saying is that many like yourself have made such claims over my past 20 years of simming

All have failed

But who knows, maybe your different?

Maybe you are the one to do it?

On that note, don't take this wrong, but talk is cheap!

Do it and than lets talk about it!

My guess is the main reason it has not been done is that it is over kill from the get go..

That is to say the benefits of it are so small that most would not even notice the difference..

At the human level that is!

Yes as I pointed out, FLIGHT Unlimited tried it back in 1995, and as I noted in my last post, I don't know of anyone else that has tried it since.

LOL

Trust me, we are as small if not smaller than 1C when it comes to budgets
