points_plus & points_minus

‘points_plus’ is the number of points a team has earned based on your scoring system (2 points for a win, 1 point for a tie, etc), ‘points_minus’ is the number of points their opponents have earned against them. In other words, if a team has won 6 games and lost 3, using the above point system they would have ‘points_plus’ of 15 ((6*2) + 3) and ‘points_minus of 12 ((3*2) + 6).
