Looking at Condorcet:
      Bullet voting, ala Plurality, is permitted.
      Approval, also permitted.
      Ranking, approving but showing difference in liking, permitted.
      Rating, being able to indicate strength of difference in liking,  
not permitted or required - meaning no need or ability to compensate  
for what other voters might do with such.
      Summary:  While the Condorcet voter can approve of more than  
one, there is no requirement for indicating difference of preference  
among such.
