The language in the brackets "more often than the other way around" needs to be different.

Juho, if you could take the following original and graft your (3) into it, that makes it something to compare to.

Here is their (non-Condorcet RCV) original:

________________________________________________________

NOW, THEREFORE, BE IT RESOLVED that, for the purpose of placing a charter change question on the March 3, 2020 town meeting election ballot, the City Council hereby refers the following question amending City Charter § 5 to its Charter Change Committee for review and recommendation to the full City Council by its December 16, 2019 meeting, in order to reintroduce ranked choice voting for the election of the City’s mayor, city councilors, and school commissioners:

§ 5 Election to be by ballot; method of election:

All elections of mayor, city councilors and school commissioners shall be by ballot, using a system of ranked choice voting without a separate runoff election. The chief administrative officer shall implement a
ranked choice voting protocol according to these guidelines:
  (1) The ballot shall give voters the option of ranking candidates in order of preference.
  (2) If a candidate receives a majority (over 50 percent) of first preferences, that candidate is elected.
  (3) If no candidate receives a majority of first preferences, an instant runoff retabulation shall be performed by the presiding election officer. The instant runoff retabulation shall be conducted in rounds. In each round, each voter’s ballot shall count as a single vote for whichever continuing candidate the voter has ranked highest. The candidate with the fewest votes after each round shall be eliminated until only two candidates remain, with the candidate then receiving the greatest number of votes being elected.
  (4) The city council may adopt additional regulations consistent with this subsection to implement these standards.

Here is my latest BTR-STV stab at it:

________________________________________________________

NOW, THEREFORE, BE IT RESOLVED that, for the purpose of placing a charter change question on the March 3, 2020 town meeting election ballot, the City Council hereby refers the following question amending City Charter § 5 to its Charter Change Committee for review and recommendation to the full City Council by its December 16, 2019 meeting, in order to reintroduce ranked choice voting for the election of the City’s mayor, city councilors, and school commissioners:

§ 5 Election to be by ballot; method of election:

All elections of mayor, city councilors and school commissioners shall be by ballot, using a system of ranked choice voting without a separate runoff election. The chief administrative officer shall implement a ranked choice voting protocol according to these guidelines:
  (1) The ballot shall give voters the option of ranking candidates in order of preference.
  (2) If a candidate receives a majority (over 50 percent) of first preferences, that candidate is elected.
  (3) If no candidate receives a majority of first preferences, an instant runoff retabulation shall be performed by the presiding election officer. The instant runoff retabulation shall be conducted in sequential rounds. A "remaining candidate" is defined as a candidate that has not been eliminated in any previous round. Initially, no candidate is eliminated and all candidates begin as remaining candidates.
  (4) In each round, each voter’s ballot shall count as a single vote for whichever remaining candidate the voter has ranked highest. The two candidates with the fewest votes in a round, herein designated as "A" and "B", shall be compared in a runoff in which the candidate, A or B, with lesser voter support is eliminated in the current round. If the number of ballots having A ranked higher than B exceeds the number of ballots having B ranked higher than A, then B has lesser voter support, B is eliminated, and A remains for the following round. Likewise, if the number of ballots having B ranked higher than A exceeds the number of ballots having A ranked higher than B, then A has lesser voter support, A is eliminated, and B remains for the following round. In the case that the aforementioned measure of voter support between A and B is tied, then the candidate with fewest votes is eliminated in the current round.
  (5) This runoff retabulation, eliminating one candidate each round, is repeated until only two candidates remain, with the candidate then receiving the greatest number of votes being elected.
  (6) The city council may adopt additional regulations consistent with this subsection to implement these standards.
