Where to find the schedule checker
The schedule checker can be found on your schedule maker page (both LITE and PRO).
What the schedule checker shows
The schedule checker shows you a few different tables that summarize your schedule along certain dimensions:
Opponents: how many games against each opponent
Venues: how many games at each venue
Times: how many games at each start time
Week: how many games in each week
The opponents view additionally has the option to break out home and away games or to simply show totals of how often teams play each other (this is the default).
Schedule checker updates in real-time
You can keep the schedule checker open and make manual changes (drag and drop etc) to your schedule (in the same browser tab) and the numbers on the schedule checker will update in real-time to reflect your changes.
