You should have used CMs, they work.  LOL...the polygrapher tried and tried to get me to make changes but I stuck to my guns, made no changes and passed.  They can't detect CMs, as long as you're smart, no matter what they say.  I used the pucker and they said nothing.  I used mental CMs and they still said nothing.  I controlled my breathing and they only told me to stop thinking about my breathing once.   ;D ;D ;D.  That is why you see all these polygraphers on this site.  They know CMs work, of course they don't admit it.  :-X :-X
