INDUCKS ratings

Stefan,

Thanks for the info. I figured that the ratings must be weighted somehow....

I'm confused by "votes averaged over story S or over all stories"--what does "over all stories" mean, and when does that apply? When there's only one vote for a particular story, as in the examples I cited?

Could you possibly show me (with numbers) how the formula actually leads to the result in the cases I cited? That might help make things clear. 

Elaine

See the bottom of http://coa.inducks.org/recommend.php?top100=1 :

Ratings are computed using the formula shown left with r the weighed rating, v 
are votes averaged over story s or over all stories, n is the number of votes of 
each story and m the minimum number of votes required to be listed in the top 
100. Some additional formula, not displayed here, is used in the rating.
