I flew with my 302 in "relative" or "super netto" for years and it behaved
just fine. Earlier this spring, I experimented and set it as "netto".
The needle moved up to about 1.5 and stayed put (while on the ground), as I
expected it to. The problem is, it stayes biased that way while thermaling,
so you think you are going up 1.5, and the audio says so too. But, you are
not!--My TE vario and the Altimeter say "You are going nowhere!" I thought I
could mentally compensate for it but I couldn't. I reset back to super netto
and all was well again!

Just found this explanation in another thread:

"the issue being when I have set the vario to Netto in the
past, with the glider on the ground, the needle points
to about 1.5kts up....which I have just realised it
what it should do...as it is assuming if the glider
is maintaining altitude it must be in rising air eauivalent
to the sink rate"


It's making sense now. I catch on "eventually".... Ha ha!
