 UPDATE: By now I remove all events that span more than one log file. This
 lets me improve speed considerably.
 
+UPDATE: Infos from Philipp:

+"Bin außerdem gerade den Code von damals durchgegangen. Das Logging läuft
+so: Mit Start der Anwendung wird alle 10 Minuten ein neues Logfile
+erstellt. Die Startzeit, von der aus die Duration berechnet wird, wird
+jeweils neu gesetzt. Duration ist also nicht "Dauer seit Start der
+Anwendung" sondern "Dauer seit Restart des Loggers". Deine Vermutung ist
+also richtig - es sollte keine Durations >10 Minuten geben. Der erste
+Eintrag eines Logfiles kann alles zwischen 0 und 10 Minuten sein (je
+nachdem, ob der Tisch zum Zeitpunkt des neuen Logging-Intervalls in
+Benutzung war). Wenn ein Case also über 2+ Logs verteilt ist, musst du auf
+die Duration jeweils 10 Minuten pro Logfile nach dem ersten addieren, damit
+es passt."
