REG IN/OUT

The power rating in this column represents the results of games within 
this league. All teams listed on this page comprise internal games. All
games played against teams outside this league are not counted.

OUT

To correct the power ratings for games played outside this league,
the sum of errors (see analysis of each team) introduced by games
played outside the league (the 'out' column) is added and divided by
the total number of games played and then multiplied by some constant.

The sum of both terms plus the ten-goal limit correction, the quality
wins and W-L Pct factor represents the raw power rating which is then
scaled (normalized) so the top team in the nation is 100.0.
