When using Run sport and Pace date field I can see the pace increase/decrease by 5 seconds and not by 1 second
For example I run @5:30 min/km and then 5:35 min/km.
I can't know if my real pace at the moment is 5:32 or 5:38 min/km
This is something that can make really big difference..
It was like this in my very old Garmin 405 but since then it was by the second until now that I have the Epix2 pro 51mm
