[EM] Is there any profile where IRV is worse than Plurality?

[Jameson Quinn]

Further note. Burlington probably would not have happened under plurality.
Of course, the same ballots would have given the same results - but
Duverger's Law would have probably made voters act differently, so that the
Democrat would have stayed in the race.

General point: you can't just compare systems under the same ballots; you
have to look at the probable strategies from the same electorate.
