That's what our team has been doing. The calendar is there to let you know the daily activity and how many points you can earn for whatever the designated task is for the day. In addition, you get 10 points for each day you get in at least 20 min of exercise. Our team just exchanges PM's daily telling each other what we did to earn points. As the team captain, I have a handwritten chart (with rows for each day and colums for each person on my team) where I write down what each person is reporting to me and a daily tally for each day. Then when Cappy says it's time (like today) to report the totals to him, I will send of an email to Cappy with our team accumulated total so far.
this is how I'm doing it incase that helps anyone else that still feels a little disorganized about how to keep track of points for their team.
