Does anyone know why this truncation is imposed? If it’s to limit the 
amount of work needed to count the ballots, wouldn’t it make sense for 
Condorcet supporters to advocate a method which was countable in linear 
time? In practice this would presumably be Sequential Pairwise 
Elimination with an FPTP pre-ranking. If you insist on a quadratic time 
method and accept the corollary of ballot truncation, I don’t imagine it 
will work very well. Or am I missing something?
