Here is the txt export for the dive show in the graph. Notice Dive Time is 00:00 (it is also 00:00 in all the dives shown in the PC interface software). Also notice Surface interval does not show seconds. It should be 00:07:39. And of course the last 5 seconds of the dive show the max depth which accounts for the blip in the graph.
