TLBTLD states that one should control their breathing as to take even breaths lasting 2 - 4 seconds. In this sense, it seems that one should control their breathing from the initial moment one is hooked up to the machine all the way until the end. Can one not worry about their breathing and only alter their breathing pattern during control questions and let there breathing go "normal otherwise? In other words, does one really have to be conscious of their breathing throughout the whole interrogation? This could certainly be a chore if the polygraph were to take two hours.

Thanks for the info. What about my breathing pattern? Should I try and control it as it states in the TLBLDT, or should I just use a normal breathing pattern and only change my breathing when I encounter a control question. If a try to control my breathing throughout the test--while I am hooked up that is--will it not be obvious to the examiner? Thanks!
