We had a hand where partner was playing a spade part-score. Trumps were drawn and the only loser was the ace of hearts. He claimed 5 of the last 6 tricks. The defender with the ace of hearts knew he had one trick, but then had to count how many cards were left to see if 5 was the correct number of tricks to claim. He got confused and rejected the claim. Would it be possible to present the claim to the defenders as all-but-1 instead of or in addition to the number of tricks claimed?
