When doing a bike activity at a regular pace of 20km/h (i.e. 3:00/km), I noticed sudden jumps on the ETE.
For instance, at a distance of 1km from the goal, the ETE would jump from 4:00 to 2:00.
I have noticed that the ETE seems to go back on fourth between being 1 minute less or 1 minute more than the actual ETE (e.g. 2 km from the goal, it would jump from ~5:00 to ~7:00). Apart from this jumps, the time seems to steadily decrease.
Is it a known issue ?
