Regardless, conveying the audible differences I could hear into audio terminology/jargon proved difficult for me on the test paper.
That was one area where Dr. Toole did training prior to doing blind listening tests. It didn't make sense when I first read that paper and I wondered if there was inherant bias introduced by doing that. Having gone through a session, I can understand the need.
FWIW, I did the session a day earlier without any time pressure and I still had the same problem expressing the differences.
