I don't know why 1st and 2nd place timed differently compared to others. For leaderboard timing their runs starts when screen starts to fade out, but for time that they have in the title of their videos, runs starts on the first input (when they choose "standard").

First input - 4.516 Screen fade out - 4.333

Played on Mesen 0.9.9

Mod Edit: 255 frames = 4.250
