Mark,
A most thoughtful metric.
It might lead to a very interesting way of valueing the gider market as
opposed to $perL/D.

Of course this is just L/D at 80 knots, with his 300 fpm cutoff being
an L/D of about 26.6:1 and an LS4 being 25:1.

It appears that you need (-ve) flaps to get as low as 300 fpm, but then
there are lots of missing interesting gliders. The Discus and ASW28 may
prove me wrong, for example.
