Not tested it myself, but AFAIK you can simply use EQdkp + CT_RaidTracker (plugin for EQdkp and WoW addon).
When you import an XML string there's checkbox called "Add Item value/attendees (Zero DKP)" which will do exactly that (e.g. sum up item values, divide by number of attendees and use that as value for the raid).
You might want to use the newest versions of EQdkp, the plugin to import XML strings and the WoW addon.
It's a matter of seconds to add a raid this way.
Totally unrelated... CT_RaidTracker stores the information about a characters race and such because the EQdkp plugin can automatically create characters that attended a raid but don't exist in the EQdkp database. Why it stores that information more than once is admittedly beyond me
Yours stores their race? I am using 1.4.1 modded CT_RaidTracker and post-patch it does not provide that info making my site look like this where players are all Unknown, and it re-breaks them even if I go put it in manually. Am I using the wrong version? I am mainly just using this for attendance tracking so it's a real big pain in the ass that that doesn't work properly.
