Hi, today I has done about 60 laps in karting.
So the first run (25 laps) it had a extreme good precised times, compared to Alfano (profesional chronometer) the fail is 0.05s +/-. In the Alfano my better lap was 1.10.88 and in racechrono 1.10.89. And had a very good data login from GPS.
The problem was in the second and third run, it recorded very bad, the precision was 0.5s - 1.0s I has done with 5Hz every time, so if I see the race line in the map the first run was very exact, but 2nd and 3rd very very bad. What can be the problem? The phone always I have in the pocket and the GPS don't move. The sky was clear all day

I can't say why the 2nd and 3rd runs were so bad, but it might be that your GPS is running out of battery, or maybe the hardware is failing. Try with different receiver if the problem persists.
Thanks for answer
And what about stop first the GPS before pause session in racechrono?
I will test in track, so I tested in car in route and I think work fine.
