Likewise most modern (Standard Class) gliders have a kink in the polar,
such that best speed to fly for almost any rate of climb is somewhere
around the kink. So there are in fact only two speeds to fly; at the kink
if you're comfy, best LD if you're in survival mode.

So for the original Discus (Dry) it's either 80kts or 50kts

I had the great pleasure of flying with the same English 2x World Champion
two weeks ago. His advice for modern 18m gliders was also two speeds,
90-100kts or 60kts. I tried it, it works!
