Line 36: === Setting the quota=== When all the votes have been cast, a winning quota is set. In ~~The most common formula for~~theory the quota iscan ~~the~~be ~~[[Droop~~any ~~quota]]~~number ~~which~~in ~~is most often given~~the asrange: ~~<!--~~ <math>\~~left(~~frac{\text{votes}}{\rmtext{seats} ~~votes~~+1} \~~over~~leq \text{quota} \rmleq ~~seats~~\frac{\text{votes}+1}{\~~right)+~~text{seats} -1} </math~~>. --~~> ~~floor(votes / (seats + 1)) + 1~~ ~~Other~~In ~~quotas~~practice, ~~used~~the quota is either the [[Droop quota]] ~~include~~or the [[Hare quota]]:. ~~<!-- <math>\rm votes \over \rm seats</math> -->~~ ~~votes / seats~~ ~~and the Imperiali quota:~~ ~~<!-- <math>\rm votes \over \rm {seats+2}</math>. -->~~ ~~votes / (seats + 2)~~ ~~For those keeping track, the size of the quota is then generally Hare > Droop > Imperiali.~~ === Counting The Votes === Line 184 ⟶ 173: === Ways of dealing with equal rankings === * Disallowing them, requiring full rankings Giving one vote to one of the top-ranked candidates, and giving no vote to the other top-ranked candidates (likely best done by choosing randomly which top-ranked candidate gets the vote) ER-IRV (fractional): Counting a ballot with N top-ranked candidates as 1/N of a vote for each candidate. * ER-IRV (whole votes) or Approval-IRV: Giving one vote to each equally-top-ranked candidate. Can optionally be combined with a suggestion that ballots that equally rank candidates shouldn't be able to prevent the elimination of those candidates.<ref name="reddit 2011">{{cite web \| title=Proportionality failure in STV with equal-ranks with whole votes : EndFPTP \| website=reddit \| date=2019-12-05 \| url=https://www.reddit.com/r/EndFPTP/comments/e6bt6s/proportionality_failure_in_stv_with_equalranks/f9thuy4/?context=8&depth=9 \| access-date=2020-02-10}}</ref>
