I watched the video at your link, but it wasn't very descriptive as to how the votes are actually tallied. This video does a good job of explaining RCV: this video Is there a similar video for STAR? I can see the problem with RCV now. It doesn't completely eliminate the spoiler effect, just makes it less likely. I understand how votes are cast in each system and they seem similar. STAR seems like RCV, but you can put multiple candidates in the same rank. I'm not sure how STAR votes are tallied, but wouldn't you be able to implement that same system with RCV? The only difference is same-ranking candidates. Is that the key to STAR's improvement? EDIT: Is it just this simple? You sum their score, then instant runoff the top 2?: link I can't tell if it's better or not yet. It still definitely doesn't elect the condorcet winner... which you can see from 3 voters and 12 candidates: Voter 1: 4 for A, 3 for B, 2 for C, 1 for J Voter 2: 4 for D, 3 for E, 2 for F, 1 for J Voter 3: 4 for G, 3 for H, 2 for I, 1 for J It's more contrived than the example for RCV, so I think it's more resistant to spoiler effect, but it clearly happens here. Essentially, every favored candidate higher than 1 is different and they all have the same candidate for their last favorite candidate. As you can see, A,D,G have the most votes, but in 1-on-1 face-offs, J would win most of the elections. Voter 1 likes J more than D,E,F,G,H, and I. Voter 2 like J more than 6 other candidates as well and same with Voter
