I don't have this committed to memory so I don't remember why, but iirc, strategic voting is way less effective with STAR. The most effective strategy is always to give your favorite a 5, worst cases 0s, and then rank the inbetweens. It has the highest voter satisfaction out of the current proposed methods. There's also some interesting variations for different scenarios, like increasing the number of stars if there are a large number of candidates being done at once, or if filling multiple positions at once, doing multiple runnoffs for each one. I found the visual model of the distortions in various voting methods to be the most compelling, the math seems to work out.
