The formula for calculating the top 50 Commercials gives a true Bayesian estimate: weighted rank (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C where: R = average for the Commercial (mean) = (Rating) v = number of votes for the Commercial = (votes) m = minimum votes required to be listed in the top 50 (currently 18) C = the mean vote across the whole report
