"When counting votes, STAR voting is also simpler than IRV. With STAR, you just add up the number of stars for each candidate, find the top two and then see which of the two candidates was preferred by most voters. There are never dozens of runoff rounds like with IRV. In addition to being simpler and easier to use, STAR voting eliminates spoilers, encourages voters to always show their support honestly, and always chooses the candidate with the most support. STAR voting can be used with many voting machines currently in use (with a minor software update in some cases)."
