Subject: Re: Ranked choice voting
Answering my own question - from https://www.pbs.org/newshour/p...

The computerized process of tabulating votes takes little time, but it doesn’t start right away.

Polls close at 9 p.m. Tuesday. Within a few hours, preliminary results should give a picture of how the candidates are doing based on voters’ first choices.

The ranked choice tabulations, however, won’t start until July 1 because the city needs to wait for the arrival of mail-in ballots.

The July 1 tabulation could potentially give a clear picture of who won, but the result won’t be official. Further rounds of ranked choice analysis will be done as additional absentee ballots come in until the board certifies the election July 15.
