Combine multiple Fivestar rating fields into an average I'm building a rating site and using Views to display top rated (Fivestar + Voting-api) content -- but calculating what is top rated is where I'm lost now. Here's my View:

As you can see  I've got things nicely set up, they are sortable etc. but now I'd need to add a final column showing the average score of those three combined, per node. I first thought I'd achieve this easily by creating a views template, and it was ok partially, but sorting didn't work as one would expect (since values were summed on the fly, not before the actual sorting happens).

Is there some smart way to combine values of those three relations via Rewriting - or some other means?
Would Computed Field be of use to you here? You might need to duplicate the three ratings fields with a different output (and hide them) but then you should be able to do some calcs on the result.
