Lets see what happens when some more samples of this stuff get out to test.
Maybe it's bad experimental design, equipment or technique or just maybe
it's real.
Maybe the Cirrus has a lower surface laminar bubble that this thing is
preventing by acting as a turbulator strip?
20+ years ago nobody used turbulators on high performance gliders either,
now they are common. Winglets were tested by Centrair at the same time and
dismissed as not being much good but they didn't test small ones which
appear to be beneficial.
Unless you have some special knowledge of boundary layer behaviour it might
be smart to withold judgement.
