I see your point. However, from my point of view a scientific test is that it can be subjective as well as objective. My method just happened to be subjective in this case.
I don't tend to dismiss a "perceived effect" if it makes a continued impression. I very often notice things that other people just don't perceive. For example, the satellite radio reduces the throttle response when it's on; when FM or AM or CD is on, I notice no appreciable difference.
