Latest tour questions

Hi everyone, i'm going to one of the Tour shows later this week and I have some questions. It says the show starts at 7 (doors at around 6), does the 1st opener usually start 7 on the dot or is it a little late or earlier?

Also, how long was the whole concert on average from first opener to DF's last song, on twitter and here around the start of the concert ive seen very varied answers with some saying midnight some saying like 10:15 some saying 11. Finally, how accurate is Setlist, the recent shows are showing like 14 songs including encore for DF which is a a loottttt so they play all 14 or is it something closer to 10, does it depend on what time they go on?
