You said there are ballot sets for which the Kemeny method and VoteFair 
provides different winners. How, then, can VoteFair be /mathematically/ 
equivalent? You say the differences don't matter in practice, but for 
the method to be mathematically equivalent, wouldn't the mapping have to 
be completely identical?
