After gameplay I retimed this run using https://somewes.com/frame-count/ with a console FPS of 60.098813897441 which is the Super Famicom native framerate according to http://tasvideos.org/PlatformFramerates.html and raw video framerate of 60 FPS for a total of 11420 frames or a Video Time of 3:10.333. First Frame set on first Mario sprite during intro cutscene and End Frame set on first frame the last yellow block stops spinning and I'm inside the 6.
