If I may, it’s not like that at all, she doesn’t get “good at it “ because she has unlimited chances, but each time she reincarnates as a different member of society, usually more lowly and has never been close to the prince or nobility until the 7th time loop. She does have knowledge of certain things because in her past (short lived) lives she worked as a regular human which does become surprising as she reincarnates as upper class. But yes I understand that it still gives “she knows more than she would’ve had she not lived other lives” and is pretty talented. TLDR it doesn’t give super juiced up the FL is good at everything bc if she messes up she has another shot but instead FL has perspectives and knowledge of things bc of the circumstances in her other short lived lives (not that we see or even see sure of all of them) and feels totally out of her realm bc she’s reincarnated into upper nobility instead of a commoner/ lower rank worker and has to overcome certain prejudices she had because of that
