I failed a full scope polygraph exam last year with a fed LE agency. Felt I was treated unfairly by the examiner (Was outright insulted and ridiculed), so I am filing a complaint.

In about 2 weeks I have a new CI-only poly coming up with an intelligence agency. 

I have disclosed that I did have the previous poly and the problems to the security investigator and HR folks, but I am concerned about disclosing to the examiner himself at the examination.

Since that dismal polygraph, I have done a lot of reading about polygraphs, including many of the documents on this website, so I have a better understanding of the process.

I am concerned that if I disclose any or all of the following:
1 - I had a previous poly which I "failed"
2 - I am filing a complaint against the examiner
3 - I have read a great deal about poly technique

That the new examiner may view it prejudicial against me. I could be accused of using countermeasures. Or worse, this new examiner could be buddies with the old examiner 

What do folks on here recommend?
