In the achievement 'Inquisitive', it says that to achieve it you must maintain a 'positive question record'. What is this?
According to this meta post,
A positive question record means you don't have too many closed, downvoted or deleted questions, overall. The formula is (TotalQuestions - Negative - Closed - Deleted) / TotalQuestions ≥ 0.5. Questions that qualify as Negative and Closed and Deleted count three times in this calculation!
