Thanks to a more consistent development in the human execution of the Flagpole Glitch (FPG), the SMB community has been slowly chipping away at this record, 21 frames at a time.* This is the most recent development! *In kosmicd12's words, "There's something called the 21 frame rule where it's only possible to save time in 21 frame increments. In some levels you could waste 20 frames and lose no time, and in some levels if you waste even 1 frame you will lose 21." Edit: Whoops, this already got broken! RIP Kosmicd.
