First, as you should know, there is no way for a log submitter to mark a
'dupe' in a Cabrillo log... nor to mark points, nor to mark multipliers. So
your question really goes to how the sponsor processes the log to match up
qso's and determine NIL. As I understand it most sponsors use a method that
if any qso matches between the logs then there is a match and no penalty for
the dupes... there might be a very few exceptions for those contests where
exchanges have to match exactly in both logs for both stations to get
credit.
So the key is for all entrants to always log dupes. That should be the one
and only key point... one which some stations still refuse to acknowledge.
During CQWW SSB we had a several minute argument with a Caribbean operation
who said we were a dupe and refused to give us a report or log us again even
though he was definitely not in our log. He of course would have saved
himself a NIL+penalty+lost time arguing if he had just logged us again.
