The stealth attack requires some advance preparation. You need to know when to attack and have all the materials ready. The idea is to take a week when you will have some time to get as much as possible written on a particular chapter. You won't necessarily finish it: the idea is to sneak up behind it and get a lot done before the chapter or article has time to put up any defenses. If it sees you coming and you lose the element of surprise then it will never let you get a lot of work done on it.
Once you get 80% of it done you will basically have won. The article or chapter will no longer be able to put up serious resistance.
