Pro Sites Statistics


I'm working with the Pro Sites plugin. Can anyone help me understand these few things in the Statistics page? (I'm using the paypal express gateway)

#1 How long until the charts populate? (I have run multiple real transactions all day and I still can't get the charts to populate with data)
#2 Where do I look to see the number of people who have ACTIVE PAYING SUBSCRIPTIONS for a Pro Site at any current moment.
#3 Does the top "Active Pro Sites" number always count 1 extra Pro Site on a multisite installation? I haven't been able to get accurate data from this number and I'm trying to understand why it is off.
