FIMing is different than topping. In order to FIM, which I've never been able to figure out how to do properly, you need to cut a certain shape out of a new shoot at precisely the right spot. When you pinch off a shoot you get two new ones. When you FIM properly, you get 6 or 8 new ones, from what I've read.
