Speed ​​jumps

Driving on a flat road (equal number of watts), on the exported file you can see jumps as shown in the screenshot. On the EdgeI did not see this, only after the export (on strava). Someone I already saw had this problem, but I can't find the post. The counter did not save the data every 1sec and here was the problem.

Latest official soft.

Edit.

Look, my friend has the same thing.

Edge 840.

Remember that these jumps are not visible on Edge while riding, only after export.

Next frend:

Edge 1040.

Everyone has the most accurate GPS option set (L1 + L5)

1:44:22, 1:44:23, 1:44:24, 1:44:29 (here's a jump in speed).

Unfortunately I don't have access to a computer. But everyone has this problem so take any file. Example: Michał Kwiatkowski on Edge 1050. www.strava.com/.../10792
