This is a tough one, because you don't want to waste your time on jobs that wont pay you what you're worth, so stating that you make X and need X + .2X is a good way of weeding out the crap. The author does sort of advise this with the notion of giving a salary requirement, but I've had friends who've used this term and companies have ignored it, thinking they are bluffing. Also, I do see how you could short change yourself if their actual budget was higher when you state your salary or salary requirement. I've found the best thing to do is to apply to multiple places and see what kind of offers you get (and then to pit those offers against each other).
