Right, so for things like college basketball tournaments here (US), all the teams in the tourney are seeded, which means ranked based on their records to date before the tournament. The highest seed plays the lowest seed first, and if the number of teams in the tourney is not a power of 2, the top handful of seeds get a "bye" and get to skip a round. The idea is that the better seeds get an advantage by playing lower seeds and perhaps skipping a game (or 2 in some cases).
So when I saw Surface Tension as 1 I thought you had seeded the chapters based on how popular you thought they were. See example picture below. Probably much more info than you expected to get
