The Air Avionics Butterfly has developed an outstanding reputation as having a competitive advantage for its ability to "instantaneously" calculate wind direction.

Does the CNv (with latest 3.3.3899 or beta 3.4.4089) calculate wind as quickly as the Butterfly?

T8, what is the wind direction update rate of the CNv?

If anyone has experience using both varios at the same time, please share your opinions.

The Air Vario updates the wind once a second and calculates it much more often than that.

When I first began using it, I was skeptical, but have come to pretty much believe what it says. Every time I thought it had a surprising value, in any situation I could confirm, it was correct. I have discovered convergence lines, shear lines, and wave using it. I have also discovered some local weather patterns which can be exploited, no one else seems to know they are there nor did I, until the Air Vario.
