Well, I really think that you got your answer. If Judy R sees two
different claims coming in from the same person/same flight she is
going to see if there were two declarations. The big question is,
which claim will not be validated? I think it will be the one that
goes with the declaration with the earlier time (stamp).

I hate to interfere, but IGC Sporting code SC3-1999-AL5, page 14,
article 4.2.2 a, says "the LAST (emphasis mine) declaration made
before take-off is the only one valid for the flight, but a
concurrently flown and different competition task is allowed."
I agree, one declaration per flight; the last, whether electronic or
on paper. We're just lucky to live in a place where one can conceive
of multiple tasks/records on one flight!
