With respect, determining flight capabilities along the entire flight envelope in direct law is a straightforward mathematical and observational endeavor - as opposed to putting drugs or biologics in a human body that is immensely variable. Why, even the patient's mental state (happy/sad etc) may affect the outcome, whereas a happy airbus performs just as well as an unhappy one*
I think PJ2 may say however, that a 'happy airbus' will "go around again after a bounce' but the 'unhappy airbus' will just roll over and have a cigarette - not sure what that means, you may want to try it in a sim!
