[Organizers] Pay split at techno-contras

There's been some discussion before on SharedWeight about pay formulas for staff at contra dances. For example, see the callers' forum archive for June and July 2011, as well as some of the recent posts on the subject "Accounting for numbers". I have a question that I don't think I've seen discussed before. If you've organized or performed at "techno contra" events that feature a DJ instead of a band, what, in your experience, is the usual division of staff pay to DJ, caller, and sound tech? What about at "techno-live" events with both a DJ and live musicians? Thanks. --Jim
