Hello, ANN newbie...

Question Subject says it all, and error reporting script doesn't seem to handle this, so...

Titles have to have at least 4 ratings to have a ratings section.

Now, if it's a popular title and it's missing a rating section then it's a problem. Looks like it might not be, in this case.

Hope that helps.

That's for manga. Ratings of anime and related audio / visual titles need at least 6 to be shown and calculated.

Ah, I see, but then if it's not shown in the title why is still shown in the best rated list?

Seems the Best Rated List should also be upped to six, no?

Since your curious Magus, Rozen Maiden is #660 at 7.01, in best rated (wieghted) with 5 ratings.

That's weighted average; I was talking about ratings with bayesian estimate. See the difference:

bayesian estimate wrote:
This rating only includes titles that have at least 6 votes. The bayesian estimate is a statistical technique used to reduce the noise due to low sample counts. In effect, the less a title has votes, the more it is pulled towards the mean (7.1567). In other words, these are the titles that many people agree are great.

weighted average wrote:
Titles with less than 4 votes are removed from the listing but are still counted in the ranking. This explains why there are gaps in the "#" column. The rating is an average of the scores given by voters, weighted to give less importance to users who tend to only rate very high or very low.

Go for bayesian estimate; it's statistically more meaningful.

Oh, I know, my point was weighted average should be raised to include titles of only 6 or more and not those with 4 or 5.

It's a bit strange clicking on a title in the weighted average and not having a ratings section in that title.
