I have Fivestar installed and worked correctly with VotingAPI and Userpoints, configured so the author of the node receiving the fivestar rating is awarded the points. See here for example
To do this also using this add on module http://drupal.org/node/241268#comment-1187208
What I am wondering is how to change the value of the points? It is currently awarding 20 for 1 star, 40 for 2 stars, 60 for 3 stars etc - I want it ideally to be -10, 10, 20, 30, 40 - if the negative value is not possible then 10, 20, 30, 40, 50

Is this a simple fix? Any ideas how to do this? Can pay either for instructions of how to do it myself if it is simple or pay someone to actualy make the necessary changes.
