Over did countermeasure?

[Bigthing101]

Hello, I did a polygraph awhile back and employed mental countermeasures. The polygraph examiner showed me my chart and said your reactions to these questions are "12 standard deviations above the norm". They were all control questions too so Im thinking maybe I did things too well and need to finesse the countermeasure use more. I had such a strong reaction to just mental countermeasures so I dont see how poly examiners cant see the reactions from sphincter muscle/ tongue biting countermeasures.

By the way Im pretty sure I failed that one since I was not continued in the process, I have however passed others since then by just using the breathing techniques.
