It worked very well. Knowing how much the author gets and seeing it go up and down makes me feel empathetic and makes me think how I'd feel if I were the one selling. I always find that when payment pages are set up this way that I'm not being "sold" something but instead like I'm being offered something useful. It also makes the whole thing feel more human if that's the right word. Payments are almost like adversarial type situations where one party is trying to take money that you're protecting. When it's set up like this it helps break down that attitude and shows you how both you and the seller are helping each other.
