Reminds me a situation back in the 70's.  We got a call from a guy who had
just bought a used Hughes 500C helicopter.  He said the A/C would not
perform per the spec.'s in the Flight Manual and the engine checked out, so
it had to be our airframe that was causing the problem.  Did a bit of
troubleshooting over the phone, I asked about blade condition, but neglected
to ask if they were clean and waxed.

Well, I took a little trip up to Oregon to see if I could help out.  Seems
the A/C was stored in a hangar that had a lot of birds in it.  Bird crap was
all over the blades.  We washed and waxed the blades and hook weight
improved about 400 pounds!  Boy, was he red faced!  He bought me a very nice
dinner though. LOL

In reference to the critical wing.  Years ( lots a years ) ago when I was
flying piston helicopters, gross weight was not something you thought about
but rather how much you could lift.  When a very heavy lift would come, I
would clean all the bugs off the blades and wax them.  Then you could lift
more than the next guy and therefore always had a job.  That probably gives
a demo of how laminar separators can be effective.  Then in later years
flying jets, vortex generators greatly changed the flying characteristics,
especially at flow separation.  I would think the very fast guys are or
should spend as much time with drag/lift and airflow as they do with
engines.
