Note β€” Approval counts estimated from 5,408 ranked ballots using favorite_viable_half method
Details

The 'favorite_viable_half' conversion algorithm: find the candidate with the most first preferences, and then determine the minimum number of figurative seats that would need to be open in order for the candidate to exceed the Hare quota with the given first-prefs. We use this to estimate how many candidates are likely to be viable candidates.

Using first-choice vote totals as a rough guide, approximately 3 candidates appear viable: Mears, Donna C., Wolfe, Forrest M., and Sharrock, Patrick I. "Ian". The approximation then assumes each voter approves up to 2 of their top-ranked viable candidates (half of 3, rounded up). All candidates ranked at or above the lowest-ranked of each ballot's top viable candidates receive approval (considering up to 2 viable candidates per ballot).

Note: For Approval, these choose_many ballots are inferred from ranked ballots.

In this election, we have 3 candidates, so the 1st choice gets 2 points, the 2nd choice gets 1 points, etc. These Borda scores are then used as STAR ratings for tabulation by STAR.
