How is an AO3 purity score calculated?
Your AO3 purity score is the percentage of statements you did not check. If you check 50 out of 100 questions, your score is 50. Our full test uses 217 equally weighted questions, so the calculator works with any question count.
What does a high or low AO3 score mean?
A higher score usually means you have checked fewer fanfiction habits, tags or tropes. A lower score means you have explored more of the archive. It is a playful snapshot, not a measure of character, taste or morality.
