Score Runoff Voting -- Example?
Has anyone found or constructed an example fake election in which Score Runoff Voting produces a different winner than plain Score Voting does?

Clay, your example is described wrongly. X=10 Y=13. SRV elects X while Score elects Y.

Clay Shentrup's example https://www.loomio.org/d/wHcaViF6/score-runoff-voting-example-?from=1 isn't strategic for Score voters as his Bob and Alice haven't used their full range. Can anyone think of a realistic example with strategic voters where plain Score and SRV give different results?

If the race was close but one candidate Felix had received a lot of 4s from a very broad group of voters and also gotten mid range scores from most other people, and another candidate Dominic had received a lot of 5's from his supporters but mostly zeros from other people, Score Runoff Voting (now generally called STAR Voting, Score-Then-Automatic-Runoff) would often elect Felix. Felix had received high enough scores to make it to the runoff, but less than Dominic. On the other hand Dominic was seen as a nicer guy and was preferred by more people. More voters would be happier with Dominic in charge so this is a better outcome for the electorate as a whole.
STAR Voting prefers a candidate with a strong coalition over one with a strong core.
Someone else can probably create you en example with numbers. That's not my strong-suit.

Bob: x5 y4
Alice: x5 y4
Eve: y5 x0
X=10, Y=13
SRV elects X
