i had a homemade vertical tube sticking up just behind the turtle deck

with or without it. Perhaps that drag reduction is why I've had so many
long flights this season

AFAIK none of the simple vario+averager type instruments have electronic
TE compensation - the B.40 and V.1000 certainly don't.

If you do get a pressure sensing vario, as opposed to a capacity flask/
flow type, and retain the Winter, you should at least glance at this:
