I wouldn't say it if it wasn't correct. I don't want to compare apples to apples, and the game has never tried to do that. All plane performances have been tuned so that standard values are being achieved in Crimea atmosphere, give or take a small margin for many planes and give or take a large margin for a few.

This is why I have pointed out that you'll often see too low speed values if you use il2-compare data from the flight test map - hardly problematic, considering that planes generally are modelled to match best historical data found, 5% give or take. As an example, TSAGI values for the La-5FN: 590 on the deck, 645 at altitude. Crimea 584, 644, FlightTestMap 575, 633. This tendency is there for a large number of planes. Now the 2% between Crimea and FlighTestMap are not that much, well within the variance of real life data and inside the limits of the game, so eventually it doesn't matter.

The impact of using a non standard atmosphere as in game standard has zero impact on the relative performance of planes, and Crimea has been used because it was one of the first maps existing. So tests could be made on it.

Anyway, I'm not going to publicly discuss details of flight model making, so that's all from me. No matter what, you've produced a valuable set of data and hopefully you can deliver more real life reference for the interested audience.
