The scoring is each round is worth an extra point (1st round 1 point, 6th round 6 points). So with you being up on Sias the next closest Buzzz win choice exactly 6 points, and this round being worth 6 points even if Buzzz wins you will tie you in points. The tiebreaker the site suggests is who got their bracket in first and I can't think of a more fair way to do it. So yea, Im 99.9% sure you are assured a victory either way by 2 hours and 49 minutes
