AA Butterfly versus CNv LCD wind calculation

I have flown with the Butterfly for three seasons. It was difficult to install as its sensor unit needs to be mostly well clear of any magnets or any moving ferrous control rods. It turns out that most of our gliders have been magnetized a bit in their lifetime. Dave Nadler told me that they tried to incorporate some sort of compass data in the SN10 but were unable to overcome that obstacle. After moving all speakers behind my head and getting the inertial sensor unit away from moving metal I finally got it working. It has some built in compensation which works for some weak standing magnetic fields but not moving ones, such as a control rod or speaker magnet. That took most of a year to sort out. It does work as advertised, giving real time wind information. The question is, does that help in finding and centering lift?
Years ago Al Leffler helped me learn to fly the Mojave shear line on blue days. He said that when, in doubt, the lift is probably downwind. That was and is good advice. In the west most of our flying utilizes some form of convergence. Over the years the phenomenon has been called, DEW line, shear line, convergence, and most recently "energy lines. I mostly fly from Siskiyou County airport in Montague, CA, We have a convergence that routinely sets up east of mount Shasta and extends easterly for about 50 miles. It appears to be a combination of converging anabatic thermals from the two sides of a wide mountain ridge, and meeting of northerly valley winds from north with the prevailing southwesterly winds from the south. The Butterfly real time winds do reliably steer you to the convergence and have helped me choose which side of the clouds to cruise. Of course experienced pilots will figure that out anyway but every little advantage helps.
There may be information displayed that would help centering thermals. Do horizontal gusts converge from all sides in a thermal?
The little wind arrow is easy to interpret and quickly becomes part of your scan and need not become a safety issue. According to Richard (Craggy Aero), the Lx Varios. (S8,S80,V7) have similar sensors and should be capable of producing similar information. I have an S80 in another glider and I do not think the wind calculations are as "real time" as the Butterfly. As a side note, after years of flying with the Ilec. SN10 I think it is still the best at computing and displaying average winds.
