A study is a step in the right direction, but the informal survey was (is) much simpler. All she has to do is sit in the eatery, look at people, and write down what she sees, if anything. Right now she cannot answer the question about how many people she can even read regardless of apparent accuracy. The next best thing is to just do the study at the skeptics group meeting.
This thing she came up with is simply unworkable from a practical standpoint.
