No.  not really.  People have reported being accused of using CMs by examiner when they slow down their breathing, etc. in an attempt to relax during questioning.  Many examiners are clueless.  They don't realize that CMs are used to INCREASE reactions on controls, NOT to lower responses during relevants.

Just follow the advise given in Chapter 3.

And DO NOT volunteer any information concerning relevant questions.  They are just fishing for something they can distort and exaggerate and turn into a "disqualifying admission".  Think of it as a police interrogation in which the detective is trying to trick or badger you into saying something so they can falsely charge you with a crime you didn't commit.  But be polite and respectful, not nasty, belligerent or arrogant.  That's their job!
