It's really a great project, however I feel that most people are actually not that "ready" to get judged objectively about their own behavior, most people shield themselves from it.
Thanks! I think part of it is unrealistic expectations for what's normal. When you read everywhere 9/9/6 is the way to go you don't want to face your "low productivity". My brain stops working after 7 hours and I get headaches if I work weekends. I hope that by putting out more data like this we can move the expectations to healthier norms again.
