It seems like Gaston has done a few years of research into combat reports (if he claims right), maybe on a project of sorts.

Aerodynamics and models are accurate, no doubt to a certain %, but have they been verified under certain and specific conditions.
For the aircraft under question, most likely not, considering the conditions of the time. That leaves us with what... theoretical values, or 'real experiences'.

Every research into the past relies on Current Knowledge and Statistics. Gaston is the Statistics of this research.
What aerodynamic proponents are arguing are static test results, if you can call them that, and not dynamic as they quiet simply do not have the same aircraft in question.
