My wife has a Vivoactive 4s, I have a Venu. She has been using the VA4s for a couple of weeks now, I have had the Venu for 6 months.
Today we set out on our normal three mile run. At 1.3 miles she stopped her run on her VA4s and restarted it, because it was showing her bad pace information (such as that she was running at a 5 minute mile pace). She had crossed the 1 mile mark on our normal route at 8:30. When she stopped it, the VA4s told her she had set a new mile record at 7:00. When we got home and I brought our runs up side by side, mine is the normal route through the neighborhood, hers shows a continuous but inaccurate circling through the fields several miles away. To be clear, the run has a familiar figure 8 shape to it, which I would expect if the location was just off a bit. Instead, the track from her VA4s has more or less a linear shape and miles away from where we were.
Anybody seen anything like this?
