Also, if the chakra of a person is fully replenished in a day, then Sakura only would need 100 days to fill her seal. Assuming she wants to go on missions and such, 3 years gives her approximately 1000 days to fill her seal, meaning she'd be running at 90% chakra every day. Seems perfectly reasonable.
