See the comments at the top of the file for a few more details. This schedule is simply a "doubling-up" of the
9 team schedule found here where the two-league, one-division each setup is applied to each of two two-division leagues.
With an odd number of teams in each league and no interleague, one team per league is always off.
Four different versions of the schedule are included in the zip file because there are four possible configurations of the divisions.
