How does the goal calculation at the first page work?

This card on the first page is calculating how much time you should do today to be in line with your goal. For example if your goal is 30h for the month, then you should do 1h/day. If you don’t do any ministry for 5 days, then it will tell you that you need to do 1h/day * 5 days = 5 hours that day to be on target to reach your goal.
