As of today (26th Jan. 2016) the statistics page for Portuguese SE shows that we have 1.2 questions/day (and we should work on that!). The same page says that we are in day 195 of our beta. The questions page shows that we have 622 questions. Using basic math our questions/day statistic should be 3.17 (622 questions divided by 196 days), but the official result is almost 3 times lower. I know 3.17 questions per day is far from 10 (considered to be good for a healthy beta), but is much better than 1.2!
How exactly is calculated the questions/day? Is this behavior a bug?
