Well that stat certainly did not apply to all of us on flight #4 on 3/12 to LAX that was to depart at 9:40pm.  First we were promised a slight delay due to an electrical reset.  40 minutes later they said one more try but if it did not work not to worry we'd still depart as it was safe to fly despite the issue.  We pulled away from the gate one hour late, we then sat on the taxi way for at least another 20 minutes and then the call that we were returning to the gate due to a fuel gauge  problem.  Well back to start and now a plane change, we did not get out until 1:00am (just 3 hours and 20 minutes late).
