Releases sold at or debuting at events on occasion have dates that don't match up. The report should check to see if releases with the "available at" or "launch event" relations release date do not fall within the timeframe of the event.

In my experience items that would be flagged by this report would usually be caused by a bad event date, i've corrected more event dates than release dates with this relationship.

It may be decided that "launch event" may not be included in the report, as it is possible (even probable?) that launch events may not fall on the release date of the item in question (I haven't seen enough launch events to make up my mind on this).
