How about the balance of those who win due to his opponent's no-show. Are they going to match-up with each other or just rise ? Technically, a person might rise up to 3rd round without doing anything. Seeing only 12 / 32 people made their matches, and 20 haven't done it after 3 days passed, its even possible in practice. Everyone should do equal amount of matches to rise to a certain round to be fair.
