I recently noticed on the Top PA album list there is the rating, the number of ratings and something that says "WR = [some number]." The only thing I can imagine is "weighted rating" but that doesn't make sense because the rating is/was/should be the weighted rating. Thanks in advance for the answer.
Curse your sudden but inevitable betrayal.

Weighted rating.  It's a nice feature that shows why an album is exactly where it is (comparing the average ratings to the number of ratings).

I thought it was "without ratings" as in only counting the ratings with reviews. "weighted rating" didn't make sense, because as TheCaptain said the ratings should be weighted.
 
What are we looking at now then?

That's impossible.

75 3.77 Excellent addition to any prog rock music collection
(5 ratings)
WR = 3.6883
Lazarus
Hacride		 Tech/Extreme Prog Metal
Studio, 2009		 Buy


This has 5 ratings, but only two of those are reviews.  Both reviews are four star reviews.  By that theory, the WR would be 4.0000- but it is not.  Let's have another example:

70 5.00 Essential: a masterpiece of progressive rock music
(1 ratings)
WR = 3.7336
Exodusarabesque
Andrew Douglas Rothbard		 Psychedelic/Space Rock
Studio, 2009		 Buy


Here is #70 in the 2009 chart, with only one rating (not even a review).  Notice the WR- much lower than 5.00!

Here's why: An album with two fives will still have a 5.00, but it will chart much higher than an album with one five.  That's where the WR comes in.  It shows why everything is where it is in the chart, and why a 3.80 can chart much higher than a 4.50 album.

I hope I have made Master Dean proud.  Geek

Ahh that makes sense. I assume the point system for ratings for reviewers still applies for the first one, and a different formula is used for the weighted rating:
 
1 - Rating
5 - Review
10 - Collab review

There are two "weightings" at work:

1. The weighting between ratings without reviews, normal reviews and collab reviews
2. The weighted algorithm used for sorting (http://en.wikipedia.org/wiki/Bayesian_average)

I think that the number currently displayed as the rating only contains the first weighting, while the one named "WR" also contains the second.

Right - such as Walter Rasby, former Wide Receiver for the Washington Redskins!  Cool
