@jjpaz Thanks for posting these results and continuing to dig into this topic. I find it quite interesting since I used to think that Suunto watches, in general, measured just a bit long. There was a time when Suunto’s GPX traces were a bit “jiggly” (some people referred to it as “zig-zagging”) and the assumption was that these wiggles added a slight increase to an activities overall distance.
However, over the past year, beginning with software 2.39.20, a fair amount of smoothing has been added to the traces and I’ve come to regard Suunto’s distance accuracy among the best. (I commented on this change over here. You’ll notice in the example I gave how the Vertical added slightly to the GNSS distance, presumably due to 3D distance, and the 955 subtracted from it, presumably due to the applied algorithm based on pace, cadence, stride length, etc.)
I find it interesting that, after working so hard to perfect their GNSS accuracy and tracing, Suunto has chosen to apply further distance calculations based on… who knows.
