Took me a while, but I think I have found the issue in the code: The next scheduled submission is not removed from the queue when the experiment is paused, but scheduling the next submission is suppressed when paused. So, I think that whenever you pause the experiment, one more submission at the next 4.9s interval always happens. If you pause long enough it happens while the experiment is still paused and you won't notice an unexpected value as submissions start again as expected when pressing start, but if you paused short enough, a submission is done immediately on start, a new submission is scheduled for 4.9s and the old scheduled submission (which should have been cancelled) happens somewhere inbetween.

Should be an easy fix which I will put into our upcoming bugfix release (once the chaos of the new semester has calmed down a bit). Do you need a test version of the fix quickly?
