No. Ideally, scores should be double checked at the end of the day. It's a monotonous job that is easy to blow through and not catch the original error (like tying your shoe). Then you have cases where the grading service sends you the wrong score as well. That happens frequently. These things usually get sorted out before 3 days because somebody on the other side will call in that they should have won. If it's an obscure event without much action, that doesn't always apply. The OP didn't specify which league, so I can envision cases that never get the correct score.

RLR speaking from experience here. Is not a big deal.
