radiators have no influence on speed

And maybe it does..

But it may be due to pilot error, or it maybe so small that it is beyond your ability to make note of it, hence the need to log the data.

With that said

I noticed you didn't list your real world data reference.. Is it safe to assume you have one? If so, how much difference in top speed are we talking about here?

10?
20?
30?
40?
50?

If it is less than 50, now take a look at the resolution of the cockpit gauges.. That alone can be a source of a good +/-20mph error.. Just another good reason to log the data

As it should

Maybe.. maybe not.. No real proof has been provided as of yet IMHO
