it's pretty obvious when someone is deliberately distorting the tracings

I would not call this a countermeasure; it's an attempt at sabotage. The truth is you have no ability to detect a properly executed countermeasure--any "suspicions" would only be a subset of your examiner bias. And yes, contributing to a decision to send somebody back to prison or lose a chance at a career is power--power that should not be ordained upon someone who completed a 320 hour course (minus time spent at the donut shop).
