Here's what I have so far. The formula is valid but I still get records of registrations received the day of the event instead of just those who registered10-days prior and earlier.
IF(conference360__Attendee__c.conference360__Registration_DateTime__c:UNIQUE <= (conference360__Attendee__c.conference360__Event_Start_Date__c:UNIQUE - 10), 1, 0)

PS. Personally, I would use a Formula(Number) like this
( conference360__Attendee__c.conference360__Event_Start_Date__c
-
conference360__Attendee__c.conference360__Registration_DateTime__c )
That way you can filter/bucket the Report over multiple Date Ranges, instead of being "locked in" to just 10+ Days
