I think you can see how that particular test was performed, it was a simple Logan looking away and Tyler A/B-ing the tracks. As I understood it though, that little test was purely to get Logan's opinion on the matter as he likely has never done a proper blind test.. The actual statement from Tyler appeared to have nothing to do with that test, it likely came from his own knowledge from studying at college and the extensive research that has been linked to in this thread already.
