That is about the right idea but you don't need a polygraph to do it. You start out by asking rather innocent questions that you know the answer to and then move to more incriminating questions (tension) and then back to easier questions and then back to more incriminating questions. You are establishing a behavior baseline on how the subject acts when honest so you can compare it to when he is dishonest. Kind of a rollercoaster to the truth.
This guy talks about it somewhat.
