they might not add much to the vario functionality, but don't underestimate the advantage of having the wind measured 20 times per second too. the butterfly vario measures all environmental influences on the aircraft like lift/sink and horizontal wind, and in theory should be able to filter horizontal gusts better than a traditional vario.

Having hardware the right hardware is just a prerequisite knowing how
to process data from all these sensors to filter out gusts is the real
difficult part. It will probably take years before really good
solutions appear. These algorithms will become closely guarded secrets.
