From my experiences, you may truly have better luck than most. Actors get tired. Actors get hurt. Actors get sick. Actors (sometimes) need to leave at their scheduled time. Props and effects break... etc. Basically, crap happens - and the later into the night it gets, the higher your chance of not getting the "full show" becomes. I'm not saying you cannot have great experiences past 2am (you are proof,) but I do think your chances are reduced. I think similar can also be said, to a lesser degree, regarding the event's opening hour(s).
