I recently started DMing Adventurers League sessions, and I've been told about DM rewards, being particularly interested in the XP I get after each DMed session.
Reading the AL DM guide, I understand that the XP is given in accordance to [a value corresponding to the average party level] × [a number of hours]. It is said that, for Hardcover adventures, the number of hours is the real amount of time the game took, but for modules, it's supposed to be the prescribed amount of time.
For the first adventure I DMed, there was indeed a prescribed duration (2 hours), but then, the next two ones didn't have any (I read the entire adventures, and nowhere would it say "Part X should take you Y hours to do" or anything similar). They were respectively from season 1 and 2 (DDEX01-04 “Dues for the Dead” and DDEX02-02 “Embers of Elmwood”), probably explaining the lack of duration, as I suppose they hadn't started to put in durations at that time.
So, do I just consider modules without prescribed play time as Hardcover adventures for the purpose of calculating my DM XP reward, or is there something I'm missing?
