How does one provide scientific proof of the self-evident?

A perfect measurement of a real-world random contour will always be perfect.
A mathematical recreation will always be an approximation.

Table driven models are only "perfect" at the (often very few) points
in the table (and even there depends upon the accuracy of the
measurements). Elsewhere they too are only approximations, the
accuracy of which depends upon how well the real world contour matches
the interpolation method chosen.

Please remember that "mathematical recreation" is a synonym for
"simulation".

And what you see in your simulator MSFS is only an approximation of
reality. A model/simulation is always a process of give & take
between the accuracy in representing various processes & effects in
different regimes, and while MSFS allows you some control over some of
those choices most of them are hidden and have been made for you.
Without real world experience it would be very difficult for you to
realize many of these tradeoffs, those with real world experience can
spot them quite easily. The advice of those who have actually
experienced what you wish to simulate can be very informative - but
comes at the cost of learning what you are missing (possibly
diminishing your enjoyment of your simulator).

The alternative, of course is,"Ignorance is bliss".

They can be made much more accurate than theoretical models, and they are
provably accurate with respect to the real aircraft at demonstrable points,
which is useful for certification.
