BTW - can anyone explain the difference between Netto and Super-Netto
settings? If I ever knew I have since forgotten.

"Super Netto" is Cambridge speak for a vario that shows you the climb
(or sink) you would achieve if you slowed to thermaling speed. It's a
cute idea... but it adds another area of "compensation" on an already
highly compensated system. You'll probably find as I do that the
device works best for thermal entry transients when it's set to good
old total energy.

More simply, super netto = netto - 200 fpm. I use it, unlike T8. If
I'm going 100 knots in 1 kt up air, I want the vario to say -1kt, not
-6 kts, and remind me to slow down. Real netto would do that too, but
I find myself losing track of which mode it's in so I fly too slow.
Some put the needle on TE and the audio on speed to fly, but I find
that confusing too.
