::: Yes, that's true. I simply meant to show that you don't get quite as much for free as it might seem like you're getting, particularly if the counts are computerized, because you have to add some numbers to correct the non-marked candidate counts at some point, however you do the precinct counts.

:::: I'm not sure I understand what you mean by "correcting the non-marked candidate counts". But if you understand that this post-processing stage requires maybe a couple of minutes of work at most for regular elections, then that's good; I just wanted to clarify that the math can be done in 2 seconds by a computer (Excel spreadsheet with the value for number of voters ranking a candidate added to all other values in that row, which will be the number of voters ranking that candidate below another candidate in a head-to-head matchup) whereas the tallying in the precincts could take days, so it's not as big a caveat as the wording of the sentence might suggest.

I ought to note that I just realized that simply counting 1st choices separately from all other ranks actually has the potential to rival the speedup produced by negative counting in many election scenarios. For Burlington 2009, for example, doing regular pairwise counting with the 1st choice trick is actually faster than negative counting. https://electowiki.org/wiki/Negative_vote-counting_approach_for_pairwise_counting#Burlington_2009_mayoral_election [[User:BetterVotingAdvocacy|BetterVotingAdvocacy]] ([[User talk:BetterVotingAdvocacy|talk]]) 21:14, 3 June 2020 (UTC) |
