The testing procedures are scientifically structured. Any modification of the procedure can have un productive effects.

When the examination is structured in the manner the test is intended to be used, the results can be conclusively determined of an individuals fidelity. The examiner can advise you as to the structuring of the questioning that should be undertaken. Remember you only need to know the fidelity, not names, number of times or where it happened. Will it really matter in your decision in your marriage and trust of your spouse?
