Again, I noticed an error while submitting a review on above album.
Before I submitted, the overall rating for the album was 4.14.
After I submitted a review with evaluation 4, the album's overall rating increased to 4.16!
 Now, this seems mathematically incorrect. What do you think?

| Could it be because of the weighting given to collab reviews? |

It's the weighted average. You submitted a review -> there are more reviews for the album -> the weight increases -> all the previously submitted reviews have more weight. I'm not sure if there's a simple way to explain ... but mathematically it seems to be perfectly fine.------------- https://awesomeprog.com/release-polls/pa" rel="nofollow - Release Polls Listened to:

^^ for the majority of times I 'rate' an album, the rating doesn't move .01 either way!!
still, I don't really think anyone is interested in my oppinion about an album, so perhaps it doesn't really matter.... ------------- Music has always been a matter of energy to me.

This is especially notable on albums that rarely get's any ratings/reviews. I edited one word on my 5 star review of Panzerpappas third album and it shooted up from 4.30 to 4.53 because of these new weight calculations ------------- RIO/AVANT/ZEUHL - The best thing you can get with yer pants on! |

^ now that's odd ... editing your review should not cause any changes. That really might be a bug in the system ... did you submit that review when you were a normal member (not a prog reviewer)?

I submitted it as a prog reviewer, but edited it after the new weight calculation changes. ------------- RIO/AVANT/ZEUHL - The best thing you can get with yer pants on! |

I don't think so, I would have noticed that. ------------- RIO/AVANT/ZEUHL - The best thing you can get with yer pants on! |

Someone(s) could have edited their review and/or changed their rating. ------------- Released date are often when it it impacted you but recorded dates are when it really happened...
