Not sure. I don't run the DkP. All I know is the person that runs the DkP has to update the DkP for each boss, and it kinda slows things down. It's a minor thing we don't have too much trouble working around .. I just thought the mod would do that and have been trying to get our DkP officer to figure it out for a while now.
We run zero sum though, and so .. when someone spends 250 points, everyone gets 10 points .. so to use the mod in-game without updating the site every time we would need it to add those 10 points to avoid anyone missing loot by a point or two because really that person only lost 240 points .. technically. That make sense?
This has been my concern about using this addon. We use zero sum as well and I have been running webdkp which updates everyone's dkp in real time. At this point I think there are enough benefits to justify switching to GRSS though.
Maybe you should just modify your dkp rules to fit the situation. I plan on making a post to inform my guild that the dkp they earn in a night will not be available to spend until the next raid. That's my quick fix for now.
I'm hoping the mentioned revamp will include instant ingame dkp updating! <3
