I've gotta think that your polygraph operator was lying to you about sending the charts to Johns Hopkins University. The university doesn't solicit polygraph charts for scoring. Employees at Johns Hopkins University's Applied Physics Laboratory developed an automated polygraph chart scoring algorithm called PolyScore that is included with some polygraph instruments. Scoring charts with PolyScore is virtually instantaneous and does not require sending anything to Johns Hopkins University.

Your polygrapher's claim that you showed "minor reactions" is perhaps a good sign, because when charts are scored as "deception indicated," it is standard procedure to confront the examinee with the results and interrogate in an attempt to extract a confession.

Few polygraph operators tell examinees, "Congratulations, you passed!" One reason for this is that a more senior polygrapher might later review the charts and reach a different conclusion. And telling those who pass that they nonetheless "showed minor reactions" helps to keep them in fear of the polygraph (and not cocky about it having been a breeze to pass).
