A fair criticism. But I did say further evidence, not concrete proof...

Inaccurate. The simulation software I've used in many other threads is based entirely on 1st principles in physics and engineering. Yes, it helps to tweak some difficult to measure or quantify parameters with test results but that is Engineering 101. This isn't the theory of relativity (hmmm well I guess that has one gigantic largely unknown fact - the cosmological constant...)
Also, for most of these simulation a kinematic rigid model would suffice over a more difficult to construct finite element model. Either way I'm not sure such a model could solver this problem definitively, just way too many unknowns. I have access to a full complement of these tools as this is my profession.
