The level leader board currently only lists the easy difficulty for each level, there are four. In addition to this, "Original" is a full game outdoor adventure category that is missing from the roster. Also, we are missing advanced 3.

Also having played through the game, All Difficulties how it currently stands only requiring everything up through advanced 4 is more like Any%, as you unlock Master difficulty after beating everything else. Beating advanced 4 does roll credits though. Master also has it's own levels such as "Technical" and "endurance" but i'm not sure what else since I hadn't played through those. Video is timestamped showing this.

Isn't the original category your own custom challenge? How would that be compared to other times?
