I agree with much of your post but:

Do you have any justification for this point? My understanding regarding flight testing for the sim flight model is that the manufacture's flight testing is primarily about certification. The sim data is taken from that as a secondary consideration and thus the test flights are not optimised to sim flight model data gathering.
By contrast a third party manufacturer (Frasca in our case) does a lot of fully instrumented test flying dedicated solely to sim flight model data gathering. As a result, the flight model data is more comprehensive.
Well that's what Frasca told me anyway! And it does seem reasonable.

It may be a bit problematic, but when the flight manual, is wrong, or has significant omissions in mentioned failure modes, there isn't much choice.
