STAR has two big problems:
- In cases like this
Red 55%: A B C
Blue 45%: A B C
Makes A win instead of B.
- If the candidate with the highest sum has a clone, the method becomes equivalent to the SV.
If there are “far right” A, “center” B, “far left” C, each of which proposes at least 2 strong candidates, even if my real interests are these:
A1  A2  B1  B2  C1  C2 
in STAR I would definitely vote like this:
A1  A2 …
or like this:
A1  A2 …
If the supporters of B and C do the same thing, you get an SV (even if the system is STAR).
STARRV with range [0,5]:
- found the candidate with the highest sum of points (eg A), who will be the first finalist.
A is removed from the votes and the score of each candidate, for each vote, is multiplied by the following value: 1 / (1 + sA / 5).
sA = score that candidate A has in the vote.
5 = maximum score of the range [0,5]
This step removes the clone problem.
- found the candidate with the highest sum (eg B), who will be the second finalist.
- Runoff: considering the original votes, the score of the best candidate between A and B is set to 5 (leaving the score of the other unchanged).
This makes the method more utilitarian, avoiding the problem 1) indicated at the beginning.
- The candidate between A and B with the highest sum wins.
It’s STARRV where the Runoff takes place as in STAR: 1 point to the best of the 2 finalists, for each vote, and highest sum win.
