I would suggest that the PIK is a notable exception to your conclusion.

It seems everything has be just dead on with this airfoil shape for it
to perform to it potential.

That seems to be what Dick Johnson confirmed with his PIK improvement
work back in the 70s or early 80s.

One glider I know of is the LS3, which has done just that I never heard
of any complains.

I didn't know it had the same airfoil but I never heard complaints either.
