Hi Cristel, hi Robert, Thanks a lot for your feedback. 1. @Cristel, yes, you’re right, I’m aware of this scheduling issue. Indeed, a big part of such ‘abnormal’ intervals is reasonably ‘short’, 55% are between 2 and 4 planned value, among 510 cases seen in 1074 probes traces over a week’s time. 2. As observed by @Robert, most ‘abnormal’ interval is actually very close to integer times of planned value. If I get your message right, you are indicating that planned measurements can be skipped for the reasons you mentioned and shall kick-off again following the previous timing, even after rebooting? Again many thanks. Regards, wenqin

479 is almost exactly twice the frequency (240), so it's basically one result skipped. Most likely the probe just didn't execute that measurement (was powered down? rebooting? was refreshing its set of tasks just at the worst time?)
