I passed but what does the number mean for the score?

[suzy]

I took a test on whether or not I cheated on my husband on 12 years and got a 5+ and that I passed with no deception. I then took another test on if I arranged to meet a man and also got a 5+ (different examiner) with no deception. How high do the numbers go for infidelity polygraphs? My husband wants to know and I can't find the answer anywhere. Someone please help me out. I thought he should be happy I passed and without any deception detected at all but he wants to know how high the numbers go. He doesn't think a 5 is good for example if it goes to a 7 or 8.
