Clubs have automatic competition tracking. These happen every week, month, and year.
The final rankings are determined around 6:00 AM New York time. Weekly rankings reset every Monday by default. However, the day of the week can be changed by admin in the settings. Monthly rankings reset on the first of the month.
You can change the start date for a club by selecting "..." in the upper right, settings, and Basic details.
Final cutoff
Check-ins must be recorded by the end of the week or month. If you check-in late and post retroactively, this will not be updated towards your score for that time period.
