I've done a bit of fluid dynamics too, and was always troubled by the number of approximations and fudges needed to make the theory work precisely
But, in the case of the NASA 'experiment', surely they are missing the obvious? The symmetrical wing section does have a long path (and a short one) as soon as an incidence is applied. The static point moves swiftly down around the leading edge, whereas the theoretical separation point is fixed at the sharp trailing edge. (In the case of +ve lift, and vice versa). Which is why Bernoulli still works.
Edited. it to is.
