[atlas] Actual measurement interval much larger than planned

Thanks for confirming. The specified frequency is indeed well respected. When there is no data-missing, the interval shift rarely exceed 14s, small compared to 240s the scheduled interval.
What intrigues me is that the exact phase/timing is as well kept after power cut and reboot.

By the way, can a measurement be as well skipped, as designed behaviour, due to scheduling issues mentioned by @Cristel?


Thanks,
