Higher speed means higher Reynold's numbers accross all of the wing,
in direct proportion. Higher Reynold's number generally means higher

I recall vaguelly that some model of the Ventus is quoted with an
extra 1/2 point of L/D max at maximum ballast.

That's the case with the DG1000. From memory it's 45 and a bit dry
and just over 46 fully loaded.
