Better Boundary Layers

No, but Dick only tested one glider, and a very early one (early '94
production). Several changes have been made in the wing since then,
such as more blowholes, adding winglets, an additional flap position,
and using NACA ducts instead of pitot tubes. My experience flying my
ASH 26 E (built in early '95, retrofitted with NACA ducts and
winglets, and no profiling or sanding of the surfaces) against DG 800s
and Ventus 2 CMs is that all three have nearly indistinguishable
performance differences.

But the 26 is the only one with blow turbulators and it goes no better
than the two gliders without. I think you just made my point.
