Moin, I do currently use iGlide, which does have a very similar wind calculation but does not require zig-zagging. My compass is somewhat accurate to less than 5° deviation after I spent some time carefully compensating it. At least in my case it appears to work fine. I usually use the circling calculation, but it gets confused when flying cloud streets with a typically very inhomogenous pattern of circling, scanning and some dolphin style. In these cases, I run the cruise wind calculation to get a new wind vector.
We have a club glider where the compass is known to be notoriously inaccurate and withstands all attempts to improve the situation so far, because even the vario sound volume affects it. In that ship, this kind of algorithm is a complete waste of time and any old school estimate is way better.
