Very simple case - two voters and two candidates. Candidate A get scores of
0/10
and 10/10. Candidate B gets 5/10 and 5/10. Under normal range voting, it would
be a draw. But to me, candidate B seems the much fairer choice. Although
there's
only a single winner, we can apply some PR thinking. Either way, 10 "points"
will be handed out to voters. If candidate A is elected, one voter gets all 10,
but if B is elected, the points are shared equally.
Normal range voting seems a little simplistic to me in terms of calculating the
winner. When I developed my own form of proportional range voting, it didn't
collapse into normal range voting in the single winner case, since the PR
thinking continued. http://www.tobypereira.co.uk/voting.html
Presumably PRV that's based on proportional approval voting using harmonic
numbers of non-integers would also not collapse into normal range voting for
one
winner.
