Every Count.It challenge has its own "stats page" providing top level stats. Getting to the stats page takes just a few clicks:
Navigate to the Live View tab of the challenge, and tap on the "view switcher" button that appears at the top of the stack of buttons on the right side of the screen, i.e. the button with two overlapping squares.
This opens a screen that show your view options. Tap on the "Challenge Stats" option.
The stats page gives you a number of key stats:
Total Challenge Points
Avg Challenge Score
Avg Daily Score
Total Participants
Percent Finishers
Activities
Group admins can dig even deeper by downloading one of the several challenge reports providing challenge activity for all users, teams, and activities. (Note: All reports are expressed in points, and no detailed user data appears in the reports that doesn't also appear on challenge logs or leaderboards.)
