I ask why didn't you compare it to P-51D data? I think I remember reading it wasn't available(?- please correct me if wrong).

Correct..

There is no real life TSPA or ROC data for a F-51D-30 running at 75" (that I can find anyway)

There is one test on a MUSTANG IV, which is an early D version sent to the Brits, but it only consists of TSPA data up to 12kft

So if we want to know what a D does at 75" we have to look at what the B did at 75" and try to account for the differences

Both the simulated D and the real B both have the same engines

The B ROC data was adjusted for the difference in weight between the real B and the simulated D
The B TSPA data was adjusted for the difference in the drag between the real B and the simulated D

With all that said, in light of everyone having issues with the letter B vs. D I am currently working on taking some P-51D data done at 67" and adjusting the data to make it 75" data. Than it will be a D to D comparison. Not sure it will work, but it is something I am currently trying to do.

But my guess is after doing that I will just end up attracting a different type of nay sayer crowd

With that said

Any nub can point out difference

Takes something more than a nub to account for the differences

That is not directed specifically at you by the way

Just the general take on the crowd thus far

Some of the post are kind of funny really

As if they thought I needed to be told a B is different than a D

Too funny!

Again, not you, you actually 'ask'

I'm referring to some of the posts where they felt the need to point that out to me.

As if after all that work they expected me to slap my forehead and go GEEEEEE Your right!
