But you still presumably need uninterrupted study time to write the cards?
Probably; depends how you make your cards (I often make a lot of notes in small notebooks, and then ankify the ankifiable bits, crossing them out as I go along; interruptions aren't that much of a problem there, but they are if you're taking notes while studying something a bit difficult).
