FYI, I changed the "Stage usage: total in day" to "=(SUM(B2:B33)/COUNT(B2:B33))" and changed to format of that field to Duration. This way it shows the average listening hours per day, even if the stage isn't completed yet. You just have to set at least one Usage time for the stages that haven't begun yet, so that COUNT won't become zero.
