The formula for calculating the Top Rated 50 Titles gives a true Bayesian estimate:

 weighted rating (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C 
where:
  • R = average for the movie (mean) = (Rating)
  • v = number of votes for the movie = (votes)
  • m = minimum votes required to be listed in the Top 50 (currently 1000)
  • C = the mean vote across the whole report (currently 6.8)

for the Top 50, only votes from regular voters are considered.

In order to appear in the Bottom 10 Titles chart the title must have received at least 1000 votes.
