IHNN doing a 1DNB run or two against a boss doesn't mean you're close. I can't imagine you can capture EoSD stage 4 books consistently, and even if you get past them, patchouli can still be a beast depending on who you use. I would be careful in shouting out "I'm close perfecting these bosses", just because you managed to only die once.
personal experience and such. ichirin and aya were great examples. had TONS of 1DNB runs of them, but it still took me forever, despite utter and crazy dedication (on aya, anyways). I'm sure you can do most of these bosses relatively quick, seeing how I have done more than half of those myself, but others will still take a while to perfect, even if you had good runs before. (looking and patchy and satori, for instance).
on a side note, while lying in a clinical room for 45 minutes, you have a lot of time to think, and I noticed that with a few exceptions (like 4, 5 if I cared to), all regular stages left are monsters. I can do miko, youmu, kogasa (also reisen, but she's the master of cheap tricks and boring spellcards, so duh. and reimu's last word is bullshit. easy as that, not doing that stage, only to fail 50 runs to that last attack that doesn't even take a life off you :V) but after those 3 (5), all I have left are either stages like PCB stage 4, so utterly boring and not even worth my time to learn them; or things like UFO stage 5, GFW extra, IN stage 6B, SA stage 4 + 5 etc etc. Each and everyone of them is going to look great once they're finished, but...the process of getting there will require a lot of...time. all of my pain. (not counting IN and TD extra. I think I could do those relatively quickly, too. With some practice)
I will probably call bullshit more than on one occasion, to be honest. calling it now :V
