xpmachina,

I don't know the answer to your question about question order.

After thinking more about your situation, I believe that if I were in your place, I would not worry about the polygraph charts at all. The whole purpose of the "test" will be an attempt to get a confession from you. Unless polygraph "evidence" is admissible in court in your country (not likely, but check with your lawyer), then it really doesn't matter what your polygrapher may think he sees in the polygraph charts.

The behavioral countermeasures discussed in The Lie Behind the Lie Detector may be helpful, but you might also try the "complete honesty" approach described in Chapter 4. Whatever you decide, I suggest that you discuss it with your lawyer beforehand.
