You may find
Thusness' model, which you're probably aware of already, more useful as I reckon most "greens" who sincerely applied the techniques would be likely to experience his 1st stage. It also makes it quite clear that such experiences are not "enlightenment" and that there is more to be done after such a realization which, to me, was one of the failings of the original RT approach; people were getting these deep insights and walking about thinking they were awakened, only to have their asses handed to them by the more difficult stages of this whole thing.
RT is all about the most direct way to realize no-self. However it is unfortunate that there is no clarity about the different degrees of self/no-self.
I have seen RT or LU "enlightened roll" people spanning all sorts of stages. Many RT or LU people did not even realized I AM, just experienced impersonality and were considered enlightened. Many RT/LU "enlightened list" are at I AM (as I AM at late phase is oceanic, all-pervading, deeply impersonal and seen as universal, thus mistaken with no-self too). Many at non dual (no-self based on Self/one mind). A few has gotten to Thusness Stage 5. But so far none penetrates into stage 6 including Ciaran (who himself is at stage 5). Ciaran does not have clarity on the degrees of no-self and so this problem occurred in his students. He has confused for example, Eckhart Tolle, who realized the I AM (first two Thusness stages), with his no-self insight. Actual Freedom teachings on the other hand, has more awareness on the different degrees of no-self, also it is a more gradual method than RT and has its own particular emphasis (e.g. On eliminating "affect") but as I realized more on anatta and emptiness I discovered that even AF teaching is also not quite complete. Nonetheless these two teachings did serve as an important condition in 2010 for me to penetrate into anatta. Later, I saw their inadequancies and more recently I'm drawn to other teachings like Soto Zen Dogen studies, pali canon suttas etc. Not saying that AF or RT is not valuable, as it can be valuable at certain point of the path, and also Advaita used to be my main focus earlier on. Pragmatic dharma - whatever works.
So anyway, my point is, it is quite impt to have some awareness on the different degrees of no-self or the different degrees of self/Self (though understanding there is no hierarchy, only different insights and experiences). One of the issues I covered in my article: http://awakeningtoreality.blogspot.com/2011/12/experience-realization-view-practice.html
Anyway LU owner Illona asked me to write an article for their website. I have dragged on for a long time due to lack of time and inspiration. I might have an idea now.
