According to their official website, 'every team has an offensive rating that represents the number of goals it would be expected to score against an average team on a neutral field, and a defensive rating that represents the number of goals it would be expected to concede.'
In addition, they said: 'These ratings, in turn, produce an overall SPI rating, which represents the percentage of available points. A win is worth 3 points, a tie worth 1 point, and a loss worth 0 points - the team would be expected to take if that match were played over and over again.'
These ratings change week on week, depending on performances.
