The 1st place team for each Ultimate League is listed on the Leagues Strength page on the Community menu. Teams are ranked based on their League Strength Factor (LSF); an explanation of which is at the bottom of the Leagues Strength page.
The LSF is an effort to determine the overall strength of a league. For example a league with numerous team errors might indicate some weak teams, which in turn might inflate the number of wins for the 1st place team. Without the LSF two teams with the same number of wins might appear to be equal where one actually plays in a tougher league.
The league strength standings are listed on three boards (National Leagues, American, and All-Universe).
