Thanks for the links, I hadn’t come across range voting before.
Like pretty much every voting system ever, it still allows for tactical voting (You naturally give your preferred candidate the highest possible score, but the optimal scores to give for the other depends on how other people are voting). It makes me wonder if that’s a thing that voting systems can’t get rid of (well, apart from degenerate things like the “dictator” voting scheme).
How about a system that picks a voter at random and uses their choice? This way there’s no incentive for tactical voting. But it still violates your strengthened version of IIA because a candidate can steal votes from another.
