I was browsing YouTube when I found this video that shows how Dio and Jotaro's fight has lasted since Kakyoin's death in canon.
"Man 4 episodes just to show a 3 minute fight..."
But even though a 3 minute fight would make sense as Jotaro literally only had a few minutes to kill Dio and save his mother.
But what do you think of this video by Dogmunch? How long should Josuke and Kira, Giorno and Diavolo, Jolyne/Emporio and Pucci's fight have lasted canonically?
