Line 234:
During the initial ranking of candidates, two candidates may have the same approval score.
 
If equal Approvalapproval scores affect the outcome (which only occurs when there is no candidate who defeats all others), there are several alternatives for Approvalapproval-tie-breaking. The procedure that would be most in keeping with the spirit of DMC, however would be to initially rank candidates
# In descending order of Approvalapproval score
# If equal, in descending order of "GradeBucklin Point Average" (i.e., total Cardinal Rating)count
# If equal, in descending order of total first-, second- and third-place votes
# If equal, in descending order of total first- and second-place votes
# If equal, in descending order of total first-, second- and third-place votes.
# If equal, in descending order of "Grade Point Average" (i.e., total Cardinal Rating)
With ranked choice ballots, the Bucklin count is determined by first counting all first place votes, then successively adding in lower preference votes until one candidate has more than 50%. This is a graduated form of approval. When an approval cutoff is added to the ballot, however, we make this additional change -- the lower preference votes are not added into the Bucklin scores if they are below the cutoff.
 
==== Pairwise Ties ====
When there are no ties, the winner is the least approved candidatemember inof the definite majority ([[Techniques_of_method_design#Special_sets|P]]) set.
 
InWhen the eventleast-approved member of the definite majority set has a pairwise tie or a disputed pairwise contest (say, margin within 0.01%) amongwith two members of the definite majority set, one of which is the least-approvedanother member of the definite majority set, there is no clear winner. In that case, thepairwise tied contestties could be handled using the same [http://wiki.electorama.com/wiki/[Maximize_Affirmed_Majorities#Compute_Tiebreak |Random Ballot]] procedure as in [[Maximize Affirmed Majorities]].
 
OrAlternatively, the electionwinner could be decided in that caseby using [[Imagine_Democratic_Fair_Choice|Democratica Fairrandom Choice]],ballot whichto chooseschoose athe winner by random ballot from among the definite majority set, as in [[Imagine_Democratic_Fair_Choice}Imagine Democratic Fair Choice]].
