    Well, whenever I rate a resource for the first time (aka when they had no ratings beforehand), it seems to sort of average it with the old rating (0.00, of course).

    Thus, for example

    8 became 6.60

    7 became 5.60

    and such.

    I noticed the same apparent "correction factor?"..."adjustment curve?" when I first began rating resources.

    I believe that the rating system is set up that way by design.

    As more more votes on a resource are tallied the effect becomes less. Ralle, Daelin or other good programmers/math wizards might be able to explain exactly how the determinate algorithm functions.

    Who wants to do the math? *blerg*

    I was just saying it's sorta silly to average the first vote with nothing in particular ><

    Any rating is just useful by mass voting, unless the counting system is not really needed.

    It's fine how it is.

    MAYBE A BUG, BUT YOU CAN VOTE THE SAME RESOURCE MORE THAN ONE TIME, IT JUST NEED A PERIOD OF TIME BETWEEN YOUR VOTINGS.

    (this period of time I do not know exactly, maybe 24 h)

    num = number of ratings
    avg = current average rating
    x = new rating (1 to 10)

    ((num * avg) + x) / (num + 1)

    That's one algorithm to use...

    Unfortunately, once you starting getting a lot of ratings, it starts to become inaccurate due to roundoff and lack of floating point precision.

    $amount = the sum of all ratings.
    $hits = the times the resource has been rated.

    $rate = $amount / ( $hits + (1/4) );

    This way, maps only rated 10, once, will not appear on the top of the list.
