What on Earth is Low%, and what does it take?

Next to the button to post a submission is the rules.

The rules are:

Beat the game as fast as possible without grabbing any items. No lighters, potions, or weapon upgrades are allowed. This means defeating Jason on all three days using the stone only.

Timing begins on the press start screen (not from the mask screen, as it automatically leads to the press start screen afterward) and ends when the final attack hits Jason.

Perform on original console if possible. You may submit emulator times, but they will not be considered official and are hidden by default. If using a flash cart like PowerPak, reset from your NES instead of the menu.

Hope this helps!
