command line tool: Spikes/Outliers in live monitoring

Got unexpected outliers/spikes in the livelog data when using the monitor command

rss2i -p /dev/ttyUSB3 monitor -d 6 -n 1

with RSS2I device 6 at /dev/ttyUSB3 within the following setup:

frame 0: dev 9 @ 2417 MHz
frame 1: dev 6 @ 2417 MHz
sync: 100 cycles ! 1 vdevs

Actual Result

This is a screenshot from the livelog monitor. The cycle indices are not up-to-date (I'll probably file a bug report for that separately). You can see a lot of outliers/spikes within the left three quarters of the shown data.

Expected Result

A plot of the data, that were downloaded afterwards, does not show these outliers/spikes. The additionally plotted constant line is at -33.8 dBm.
