Progressive Rock Top Albums / all subgenres - all record types - 1955 - all countries

Based on members ratings & PA algorithm

Here is some details about how we calculate the average rating of an album and the rank of an album.

Average rating: The classic calculation of the average but more weight is affected to the ratings of progarchives.com collaborators and to ratings with reviews:
- Rating only: Weight = 1
- Review by members : Weight = 10
- Review by PA Collaborators : Weight = 20
Rank of an album: We use a calculation that compare an album average ratings and number of ratings over all others albums in the query using this theory (http://en.wikipedia.org/wiki/Weighted_average) to create a variable every query "QWR" (AKA: Query Weighted Rating) use for ordering.
By default, only albums with the average ratings above the average ratings of the requested query are displayed in theses lists, you can control this value in the filters
