BTW, the "rating" comment is: Rating: 3.3, by 1 users You already rated: 1 Yes, this is as designed Peter. When the number of votes is small (no matter good or bad) the rating is normalized towards the average = 3 although I would expect 2.7 in your case and not 3.3. Honzo, can you please clarify this? Thanks! (In reply to comment #2) > Yes, this is as designed Peter.

We use Bayes average for calculating overall average. It corrects plain average depending on number of votes plugin has and what is overall average in ratings and overal number of ratings etc.. http://leedumond.com/blog/the-wisdom-of-crowds-implementing-a-smart-ranking-algorithm/ |
