Obs cop, have you looked into published papers and theses from university students? I can't say I've ever seen anything specifically about Tornado but modelling aircraft performance based on published data (and stopwatch data from public demos) isn't unknown in the student world. While the nth level of CSAS handling characteristics won't be available, Tornado is still just an aeroplane of known geometry, weight, thrust and so on. If a particular feature isn't readily available such as cg position, an educated guess will often give a surprisingly good approximation.
