The "questions per day" statistic in this page seems wrong. The project has 277 questions in 56 days, which, to me, makes 4,9 questions per day and not 4,4 as showed currently. How so?
If you hover over the number, it gives a bit more detail: "5 questions per day on average over the past two weeks". Originally we were doing it for all time, but the rate usually changes over the course of a beta so we changed to doing it for only the past two weeks.
