I haven´t seen that you have cancelled this because I ´ve just read the first part and I´m also practicing it at the moment. It seems very believable to me that I can recognize notes that way more easily. Although I know that my ear also needs other qualities like hearing rythmn, key, etc, but I´m sure you know that even better.

By the way, I´ve just found a very similar lesson with similar context of a guitar teacher on http://www.cyberfret.com/ear-training/index.php
