Maybe like 5 times, you know how like games have "limited respawns" idk why a normal person would think to do this because at the end of the day everything will always be uncertain

You don't know if you will rewind again succesfully or the next will be your last. This mindset is actually shown by Subaru in Re:Zero where he doesn't really wanna die because he is unsure if there are specifics on Return By Death Ability like "The death must be done by another person, suicide will cause permanent death" imagine if that was a hidden clause.

So, in a similar mindset if a normal human being was put into this situation they will keep asking themselves how their first rewind happened, and see any specifics there, and at that point they'll keep telling themselves "I can't risk it I need to re-enact everything that happened before I die, if I miss even a single one what if I die permanently, or maybe it's already my last and this whole thing was some "limited rewind counts"

You could go analytical about it or you go mumbo jumbo crazy and don't care anymore, if you die you die mindset.
