Ranked ballots for 13 candidates are not the same as counting one ballot only for one party.  The CPC leadership ballots allowed the ranking of  10 choices.  Each choice was assigned via postal code to one of 338 ridings.  Once assigned to the riding,  the top and  subsequent round top choices were  given a weighting and points for that riding based on the number who cast votes in that riding. This happened 10 times.  Through each iteration the Leadership Party Candidate with the least points was eliminated and their points apportioned equally to those candidates remaining.   So it's much more complicated  than the recent FPTP one-vote one-candidate recount here in BC.
