I realize the above may not be what you want with all single games, but I just sort of ran with it. That gives the closest thing to balanced with 4 or 5 games per opponent.
Another option with true series would be playing:
- 1 opponent in 4 games, 2 home & 2 away, in that 4-game weekend with 2-game series hosted by each
- 8 opponents in 6 games, two 3-game series with one hosted by each
- 10 opponents in 3 games, one 3-game series, play 5 home and 5 away
Let me know if that would be preferable.
Oh, and also mention if you have any preference on start & end dates. But that is something you can easily edit for yourself in the file.
