Michael Vincent did the test from the instructions he was given. Way back, long time ago there was discovery released about all of this. Dr. Vass was very upset about the leaks to media because he had not concluded his work. I remember an email that Vincent is asking Dr. Vass about how to do the testing. A lot of posters were unhappy about MV doing the tests because in the email he sounded like he didn't know what he was doing or at least that's the impression some people got.
