You only had this issue once. Or at least you make it seem that way. Yet you "fixed" the one time issue by changing something. May as well have been possibly fixed by you changing jersey's.
Perhaps if nothing else mounted near the device created the turbulence, then it was just the angle and speed of the wind and gusts that caused your device to be off for that one day.
Once??? Nope, every time I went on a ride like this, maybe 20 in total. Then when I placed the unit on the stem, another 10 rides or so and all was well.
Not a single time did I ever need to adjust the elevation on any of my other bike(s) rides.
