How are ratings calculated?
Ratings are calculated using Evan Miller's method (based on a Wilson score confidence interval) that is self-correcting. This means that the % of positive ratings & number of ratings decide a mods position on the top charts. The benefit of this approach is a mod with 2 positive ratings will not outrank one with 10 positive ratings but 2 negative. Nor will a mod with tons of rankings outrank everything unless most of the ratings are positive.
Ratings range from overwhelmingly positive to overwhelmingly negative. The color changes depending where on the scale the mod fits.
