I have read KP and partly agree.
You look for a half way between IRV and AV.
S-TM instead is an half way to other methods:
- If everyone in S-TM voted with [worst] and [best], it would become AV.
- If everyone in S-TM voted with intermediate ratings, it would become Score.
- Condorcet (pairwise comparisons) to mix AV and Score.
- in case of tie, all candidates but 2 are eliminated on which the comparison is then made , similar to STAR.

what exactly do the letter S-TM stand for?

Am I right in suspecting that both in S-TM1 and S-TM2 there could be ties that are not resolved with the suggested Tie-breaking rules.
For instance for S-TM1 : when there are 20 candidates and 5 of them have the same sum of (adjusted )scores while 3 of them have also the same number of ratings [best] and 2 of them also have the same number of ratings [ worst]

- add something like: this is intended as a single winner method
- "The candidate who wins in the most pairwise matches wins." better: "The candidate with the highest sum of points wins"
@Essenzia I see what you are saying but this normalization is complex. The STLR is simpler to understand and would help people vote better. STLR comes with a clear and clean scale.
Yes, there are unresolved tie cases as in any voting method. The important thing is that they are sufficiently rare.
If 1000 or more voters vote, it is extremely rare that multiple candidates have the same number of [best] or [worst] just as it is extremely rare in AV that multiple candidates have the same number of votes.
Frequent tie cases to be solved are those caused by condorcet cycles and for those the solution is proposed.
"The candidate with the highest sum of points wins" is not the method I am proposing. With a similar process, there could be many more min-max strategies.
The benefits of STLR and STAR fall with the clones, becoming Score Voting. I don't think the added complexity of such methods is worth it in the long run (given that in the long run, political factions would understand this clone problem and exploit it to their advantage).
@Essenzia I do not think that the clone problem can be exploited. There will always be an individual who wants to win. If there was two candidates supported by the largest bloc of about 40% of the voters they would still fight with eachother. They would try to find more and more supporters by adjusting their platform. This means that it is not a Nash equilibrium and that the candidates would drift towards more and more support.
It is important to realize that in a system without vote splitting the power of parties would be greatly reduced.
Also, falling back to score is not something I would view as a problem.
@Keith said in S-TM:
If there was two candidates supported by the largest bloc of about 40% of the voters they would still fight with eachother.
Yes, but they would still both be supported by that 40% because they both don't want to do things that make them lose that block.
Positive the fact that they try to have the block bigger and bigger, but if the block is for example "Republican", it will remain "Republican" (as well as the 2 candidates who then end up in the automatic runoff).

The problem is that if you end up in Score Voting then you might as well use Score Voting from the start, which is simpler (but has its downsides).
