Think:

      Mapping ballots into a matrix is a required component of elections 
when using the Condorcet method.
      The mapping required for Condorcet is not part of major competing 
methods such as Plurality, Approval, and IRV.
      At most we are arguing English and grammar, for the spoilers that 
can afflict IRV when it ignores parts of the rankings are simply not seen 
as such when doing Condorcet.

Agreed you cannot map the matrix back to ballots so, if for some reason 
you want to see the ballot rankings, simply keep the ballots around.  I 
would want to see big value in such keeping before I agreed to depending 
on it.
