Hi hhonza501,
That is correct, the Event List contains events that occurred during the last sweep.
Currently, all events are logged in realtime, so an ongoing event is logged repeatedly, after each sweep, with an increasing duration. This is to ensure the accuracy of the log at any given time, and to safeguard the data in the event of an accidental system shutdown. However, we have decided to change this functionality, in favor of having an ongoing event logged only once, either when the signal disappears or logging ends, with its final duration. This change will be in the next Spike update.
Let me know if you have more questions about interference hunting mode.
Regards,
Roger
