Although my in game time is slower, I think my real time is faster because of early voice line triggering. I think the pop up to save replay/go to the next round comes up when the win/loss voice lines end for both characters. Usually your win line plays first fully and then the losing character's line plays, but if you are in the middle of a different voice line the losing line gets played immediately and your win line gets played as soon as the previous line ends. I don't think this is random or dependent on the computer used.
