The .99 means that you were found to be 99% deceptive.
99/100 and .99/1 are both representative of 99%.  Don't make ther error in thinking that you were found to be less than
1% deceptive (if that were the case,  you wouldn't find yourself in the situation you are presently in).

If you were truly truthful (hell...and even if you weren't),  then start reading The Lie Behind the Lie Detector and begin the process necessary for a retest.   

Don't make the mistake of taking another polygraph without the aid of using countermeasures.

geoge thanks for your advice i not giving in. i know i only 
told the truth i dont even have a traffic ticket. but what was odd was the  0.99 on the screen, to me that does not even indicate 1.0 %. do you know what that score meant. 
thanks again george.

dogbone,

While it is conceivable that your polygrapher was merely bluffing, it sounds like you failed. I suggest that you begin preparations for appealing the polygrapher's accusation that you were deceptive. An initial step you should take is to draft -- in as much detail as possible -- a memorandum describing everything that happened during your polygraph interrogation.

See Chapter 5 of The Lie Behind the Lie Detector for more suggestions on how to appeal.

i recenty took a pd polygraph pre-employment test 
i went thru the first set of questions and the second 
and was asked if any the questions bothered me. i said no,
i was asked another series of questions . then the polygrapher told me i was deceptive and showed me a 
score on the sceen with  0.99 deception i did not understand because i only told the truth he said i showing deceptive signs
of undisclosed major crimes he said i can get thru this if i 
just told him what they were. i said i did not know of any major crimes. do you think this was a scare tactic to try to get me to confess to something i never did? do you think i passed or failed. [color=Beige][/color]
