The SAV score of a range ballot r for a coalition C can be written as a fraction with numerator
Sum over x in C of r(x), and denominator Sum over all x of r(x). Note that when r is an approval ballot the numerator is the number of alternatives in C approved by r, and the denominator is the total number of alternatives approved by r, so this is a straightforward generalization of SAV to range ballots. ---- Election-Methods mailing list - see http://electorama.com/em for list info
