Looks like clearly the most methodical way to EQ. I might try, but alas, I never really get the feeling that I'm in the mood to listen to a bunch of test tones. I just accept that my EQ is good enough. If I wanted to make it perfect to my ears, I'd be changing it for almost every album.
That's what I did initially, then I realised this was driving me slightly bonkers and I was not enjoying the music because I was tweaking it all the time... so I set up 3 presets, a smooth one with rolled off treble, one with brighter treble and one in the middle. Once you have the basic shape correct for your ears / headphones and a few presets you can leave it alone.
This is pretty much what I use now... I do not bother trying to remove the midrange glare because it sounds alright anyway with the pad mods.
