Am I missing something I need to do to get the statistics for loot received and number of raiding characters to count all of the stuff showing up in our second DKP system? I'm currently running 2.

The statistics at the top of the page are based on the cumulative. So "total raiding characters" is any character that's attended any raid in the past 3 weeks.

For Loot Received, its the total number of items received.

Ok, but the problem I'm having currently is that the current stat is zero raiding characters and no loot since BC.

Pre-BC I ran one DKP system and the stats updated correctly. I have since created a separate (25 man) DKP system (leaving the older 40 Man one in place).

I am updating our Kara runs in the 25 man system, although no DKP is given or used. So people are getting recorded against a boss kill for zero points. Does everyone need to get at least one point from a kill for them to qualify as "raiding"?

The other issue is that the "items received" total is also not being updated (is that because people spend zero points on them)?
