Implement functionality from Drupal's Fivestar and Voting Modules.

I use Drupal 7's Fivestar and Voting modules to implement a rating system on a Drupal 7 site I am developing. The rating system uses a node and Entity Reference to rate a specific user. Each time a user submits a rating, they are publishing a new node. The rating allows a user to rate a user on four categories using 5 stars; Professionalism, Communication, Quality of Work, and Timeliness. There is also an Average field that computes the average of these four criteria. What I need is a field (perhaps Computed Field) that takes the average of all averages of all votes cast for a specific user and displays this average in the form of stars. Keep in mind that each new vote is a new, published node. I will also need a count of reviews to display along side of the Average star rating. This system will essentially be similar to: [login to view URL]
