Perhaps you can show price per LD point?

i don't think thats a relevant metric. how often do we really fly at best L/D speed? best L/D is somewhat irrelevant. If all they were focused on was raw L/D, I'm sure they could make gliders with extraodinary L/D's, but they are trying to optimize the performance over a wide range of speeds.

Don't forget the ASW12 had a 46:1 L/D in 1965!

But those guys running around in Australia at the moment and averaging up to 160 km/h (85+ knots) on task are obviously not doing a lot of flying at their 50 - 60 knot best L/D speed.
