One best makes use of the linear progression described in the book by maintaining a caloric surfeit over what their normal maintenance needs would be. It's a possibility that you'll lose definition during this process because of the two sentences before this. Some go overboard, and stay way over what they need, and they end up getting a little chubby (they also, generally, end up with the biggest numbers at the end of the progression, but that's neither here nor there). Anyway, the other side of this is that, generally speaking, it's far easier to cut down when one's significantly increased their muscle mass and has therefore a higher metabolism. So you got that goin' for you.
