Low overtime regeneration question

[NHTkenshin2]

“low: Merely an accelerated healing ability for normal wounds, allowing the character to heal wounds that would normally take days, weeks, or even months much more quickly, sometimes even in just seconds. For machines and vehicles, this would just be regenerating basic exterior damage.”-regeneration page



From what i get low regen is just accelerated normal human healing?
So how is overtime low regen a thing? That kind defeats the purpose

GT Goku has low overtime because he regained his sight after he was blinded by Eis.

I don't think that's possible for a human (without medical help), so, that'll be an example of low over time

Hmm i guess that makes sense.

Or imagine a character who had injuries and after a while he recovered (one day)
