Right now it's not too bad, but it also depends on everyone's activity, and how complicated a report is (how long do we need to discuss; e.g. we had one report which racked up nearly 30 posts from our discussion)
This week (last 7 days; very calm): 21
Week before: 33
Week before that: 32
I remember though phases like the Civ5 launch when we had 50+ per day.
