(Added STV-like version description)
Line 24:
## The result is the fraction of a vote that is allowed for each ballot identified in step 4.
# Based on all the ballots, but with reduced influence for the ballots identified in step 4, identify the most popular candidate from among the remaining candidates. This candidate becomes the second-seat winner.
 
== STV version ==
This method can be extended to elect more than two winners such as filling multiple seats on a city council where candidates are not associated with political parties. This usage produces proportional results such as achieved when using the Single Transferable Vote (STV). Unlike STV this method provides better protection against tactical voting.
 
For these purposes:
 
* Use the method described above to fill the first two seats.
* In step 1, the ballots to be ignored include any ballot on which any of the already-elected candidates appear at the top preference level.
* In step 5-2 the word ''half'' is changed to ''two-thirds'' when filling the third seat, ''three-fourths'' when filling the fourth seat, ''four-fifths'' when filling the fifth seat, and so on.
* When filling the third seat, a ballot is given zero influence if that ballot ranks both of the already-elected candidates higher than the candidate identified in step 1.  Similarly, when filling the fourth and fifth seats, a ballot is given zero influence if that ballot ranks all three or four (respectively) of the already-elected candidates higher than the candidate identified in step 1.  For this purpose, if a ballot ranks a not-yet-elected candidate at the same preference level as an already-elected candidate then that ballot is given zero influence during steps 4 and 5.
