Begin with a beginner's mind, Abbey. The folks who say they have never seen it work, mostly have never really applied the method...going through all the steps. They pick and choose or observe posts and think they are taking data. They mean well, they just dont know that observing posts isn't taking data.
Start all over. Pretend you have never done this before. You have data that tells you that you know what you need to do. Just do it. Take more data, adjust appropriately.
