Format of upcomming polygraph

[Toungebitter]

I have a polygraph comming up it is for a local law enforcement agency.  I have a few questions regarding it.  I already read the book on this website twice and I have read doug William's book.

1.  Do you use countermeasures for the control and irrelavant questions? or just the control questions in other words should you demonstrate a reaction to the irrelavant or for thatr matter to the sacrafice relavant?

2.  Where do the control questions usually come into play are they usually in the begining of the test, before and after a relavant question etc...

3.  If the series of questions are repeated do i use cardio and brething countermeasures the second or third time they are repeated.  Doug's book says to use breathing and cardio the first time then go through, just cardio response the next and I believe use mental CM's the third set if it gets to a third set.  I did not see it in TBTLD.  Or do you recomend using cardio and breathing through each series?

Thanks
