Think you missed my point, if the event is shown live on TV then someone somewhere is recording scores for every player live, so the leaderboard can be shown on TV and on the course. Who is recording scores for every group as they happen - obviously someone, otherwise the leaderboard could only be updated at the end of a round.
That's still not the official scores. These will only be official when everyone has signed their card.
Scores will mostly be updated by volunteers and there will errors on these that are updated from time to time.
