It depends on the snake
I know that each corn snake is different, and some corn snakes will eat a full meal every 2 days with no regurgitation (this is aggressive power feeding, and I don't recommend it), and other snakes will refuse to eat any sooner than 7 days between meals. So if you took a good eating young adult and fed it a ridiculously small meal, like a pinky or a fuzzy,it would eat every day with no problems. In my experience, you only run into regurgitation problems when you feed normal size meals too often, or if there is something else happening (like shedding, sickness, or you have a gravid, meaning pregnant, female).
This is all a hypothetical discussion, because there would be no purpose in doing this type of daily feeding.
