<div>rating is easier than ranking. You can express this computationally, by saying that ranking requires O(nČ) pairwise comparisons of candidates (or perhaps for some autistic savants who heap-sort in their head, O[n log(n)]), while rating requires O(n) comparisons of candidates against an absolute scale. You can express it empirically; this has been confirmed by ballot spoilage rates, speed, and self-report in study after study. </div>

<div><br></div><div>There is no need to scale rating values for MJ. In fact, it is not the intention. A vote of "Nader=Poor, Gore=Good, Bush=Fair" is perfectly valid and probably fully strategic even on a ballot which includes "Unacceptable, Poor, Fair, Good, Excellent".</div>
