We do not even know if compressibility is modelled or not. We do not have real world test figures for correct high speed dive behaviour, and a random poster's colored graphs based on cluster of guesswork figures and labeled '109' or 'Spitifre' hardly make a comparison basis.
It makes an interesting theoretical discussion but the whole thread is absolutely useless for checking the FM's validity. Unless someone would suggest the developer's should rely on hobbysts guesstimations of performance.
