What do you mean? That's what the tiebreaker is for. Problem writing is hard, especially if you're trying to distinguish between very close competitors.

The difference between those different entrants is a huge amount of time. The winning unis made correct entries earlier, and had less incorrect entries.

Compare it to a marathon where there are 9 finish lines. The more you cross, the better you did. Everyone who crossed the 6th line is ranked by when they crossed it - or how fast they ran. They probably also got much closer to the 7th line before the time ran out.
