I found that the "support percentage" formula S/(S+O) fails some important criteria for voting systems, for example it gives more weight to a vote for minor candidates, which violates the one person, one vote principle among others. "Net support" (S-O) is equally obscure and problematic. My personal suggestion is to stick with straight "approval" voting, ranking winners by the total number of support votes, rather than attempting to invent or explain more exotic systems.
If we still want to factor in oppose votes as a measure of "controversiality", we can set a minimum support percentage, rather than using it to rank directly. Looking at the support percentages for the top 5 candidates in the last election, they were within 5% of one another and the score was quite inappropriate to use for ranking. Sigh, lessons learned! Here's my analysis, I'd be happy to move to the main namespace if others want to expand on it: https://meta.wikimedia.org/wiki/User:Adamw/Draft/Board_Election_analysis -Adam [[mw:User:Adamw]] On Fri, Jan 29, 2016 at 9:28 AM Anders Wennersten <m...@anderswennersten.se> wrote: > Actually the formula used (S/S+O) is from a ranking point identical to > (S-O/S+O) (=(S-O)/(Total-Neutral).
