Given a ranked ballot one can create a rated ballot, where the 
ratings are '1st-rank' , etc. If you convert a rank to a rate and 
back again, you get the same ranking. If you convert a rate to a rank 
and back again you different ratings. Ratings express more. However, 
the two ratings will be equivalent unless the rates are intended to 
express some strength of preference. In the latter case, the ratings 
are more prone to manipulation than rankings.

Ratings are for honest voters?

Cheers.
