How are the computer rankings determined?
Rankings are primarily determined based on the margin of victory between teams in all games over the course of the season. To promote good sportsmanship, a seven goal margin of victory is considered the maximum in the rankings (i.e., beating a team by 7 goals is the same as beating a team by 20 goals).
How can my team improve our ranking?
As more games are played, rankings change to account for the margin of victory in these games. You can improve your ranking by beating or playing a close game against a team that is higher than you in the rankings. Note that doing this for one game is unlikely to significantly alter the rankings, but doing this for a number of games will result in your team's power ranking being adjusted upward.
Why did my team's ranking change when we haven't played a game? In addition to changes to your rankings after playing a game, it is important to recognize that your ranking will also change depending on how the rankings of teams you have played change over the course of the season.
