I've seen or heard of flagged posts with scores ranging from -11 to 100, but without knowing what the total range is these scores are somewhat meaningless.
What I'd like to know is:
- What's the lowest possible score (a perfectly bad question)
- What's the highest possible score (a perfectly good question)
- What's the threshold where posts are flagged as "low quality posts" for moderator attention?
[Edit] To clarify, I'm talking about the quality score that you see on the /review page, not the vote score. For example, this answer has a vote score of 0 and a quality score of 79.
