<<Fortunately, doing what is required for structural reasons also makes the airplane go fast by reducing the otherwise high trim-drag.>>

 

Dan, et al

The attached excerpts show another key reason for the reflex.  Our planes are too fast for this airfoil without using reflex.  Reflex repositions the drag bucket to coincide with our cruise speeds.  The paper on the NLF 0215 describes how this feature was built in from right from the start.
