When going over events help you understand is because you start to notice things once you look over it over and over. like with a movie you watched a hundred times you start to notice small details and mistakes that happen. it help you not just see as a whole but in small fractions.

Some generally refers to a bigger amount that a little, but is not a lot, that is probably a confusing way to explain so i am sorry
