How do you set up a bowling league schedule for 5 teams?

League schedules can be found on the United States Bowling Congress' website at www.bowl.com. They have schedules for 4 to 48 teams.

Also, there is league software available on the market, such as CDE Software's Bowling League Secretary, that have the schedules built in.

In your situation, you would use a 6 team schedule and use a BYE team.
