> I wonder what the percentage means. upvote/flag ratio?

Good guess, but no. It's a score generated by the ring detector. It's rather out of date, because the code has changed a lot since that computation was written.

huh.

I built a clone at news.intelmap.com a year or two ago, and I don't have the percentages in my admin console. Perhaps an addition since pg's exit?

I believe there's a bunch of unreleased code to do with voting rings and other abuse protection.

Comments/Points

Item 10 has 439 points and 140 comments. 140/439 = 32%, but it shows 40%.

I'm guessing it's the ratio of older user upvotes vs total upvotes.
