If a respondent is capable of chart manipulation than I would imagin that a polygrapher could do the same. If so how?

If proven could one not sue for professional malpratice?

What I'm looking for are studies or reseach on Polygraph manipulation by the examiner. Are there any available to your knowledge? 

I recently was issued a status of inconclusive on my third polygraph.  I had passed the previous two with no problems, I had quite alot riding on the job I was applying for which I was given the inconclusive result.  I was eventually informed that I was no longer being considered for the position due to the inconclusive result.  The difference between the previous two was that the examiner(asshole) attempted to upset me regarding a couple of issues;  This consequently distracted me causing my cycles of respiration to drop to about 8 a min, while being tested, which he said was way below normal(30).  I did this unintentionally, as I was trying to relax due to him stressing my out, which I tried not to show.  My relaxation techniques worked a little to well.  He seemed quite upset after testing my three times and not getting a conclusive result.  So don't fall prey to the examiner manipulating your emotions prior to the test.
