I have taken one before this one and passed.  I took this one and it was slightly different.  In the first test, I went through the 10 questions two different times with a break in between and that was it.  He unhooked me, told me all I needed was my gun and badge and I left with a good feeling.  I passed that one.  The one I just took, we went through the standard intro booklet and then he hooked me up, I felt a lot more nervous this time.  Anyway, we went through once, he then asked what i was thinking about during the question about any crimes I have committed, I said that I thought about  speeding because my psychologist asked about any laws I have broken.  he said that didn't qualify as a crime and we proceeded through the questions 3 more times with a break in between each battery.  He then unhooked me, I helped fold the poly sheet, signed the sheet and I was on my way.  Nothing else was said.  I was just wondering if I passed.  I was honest and not hiding anything or using the techniques listed.  Thanks for any feedback.  the process only took about an hour and 15 minutes by the way.

I realize that you are probably looking for an answer to calm your nerves or reassure you that everything is fine.  Unfortunately, the polygraph is much like judging a beauty contest, in that I mean it is subject to the personal bias and interpretations of each judge.  Simply because the Poly sheet didn't look like there was anything out of the ordinary, doesn't mean that the polygrapher can't just fail you based on a gut instinct.

Only time will tell if you passed or not.   

Good luck
