Hel,
I think this is such a worthwhile question. It seems to me that somewhere, a long time ago, someone said to get to the point where you use all the time. At the time, i thought that was mind-boggling impossible to ever do.

Now that i've finally learned it so that i can do it w/ the exercises of SFQ and small universe, it's not so mind boggling. I'm not thinking about breathing like this all the time though. It took me forever to just learn how to breathe from my diaphragm regularly.

Don't know if this answers your question, but that's my progression w/ this breathing technique.
