This leaderboard was just recently started and has been extended to support both FCC and CE modes.I see some tables there with one entry in each. Are those the "leaderboards"? If so, what is the point of the empty entries? To provide exercise for one's scrolling finger?
Those are just example entries. And as Thomas B mentions, It is a way to speed up new entries. Once someone is added to a new class section, the example entry will be overwritten.To prevent the need to spend time to add the listagain each time a new one needs posting.
