GPS sampling rate fluctuation in Lap Analysis

Sledgehammer

Hi, when I look into the lap details in a session, I can see that the sampling rate of the GPS signal (RaceBox Mini S) sometimes it's stable at 25 Hz and sometimes it fluctuates. Value shown is always 25 Hz, but the line fluctuates sometimes ...
What does that mean, and how can I fix this?
Thanks in advance

It means the Bluetooth LE connection is losing an update here and there. Not very serious if the update rate is high even at the low end.
