Jameson,
like you I think ratings are simpler and easier for the voter. But
it doesn't matter because ordinal ballots
can be transformed clone free and monotonically into ratings by the
technique I gave in my message
entitled
"Borda Done Right" a few months ago.
I see July 27 as when Forest described converting rankings to
ratings. Actually not much worth doing unless the ranking coder
expected this conversion (the fact that the numbers convert does not
make the associations among them fit in their new environment).
Converting the other way is easier - keep the numbers and call them
rankings. This keeps all that is meaningful for we look at rankings
for A & B and care only whether we have A>B, A=B, or A<B.
Forest described the modest effort for converting rankings to
ratings. I claim ratings to rankings HAS to be simpler since you
simply change the labels without doing anything to the numbers
themselves.
Using them also fits:
Ranking as to two values - just see to it that all A &B pairs
properly relate as above.
Rating demands also deciding on the magnitude of the differences
the voters, collectively, assign.

Why ranked and not graded ballots?
