I haven't gone all the way through FYFV because she suggests going step by step. But, she says that people should always stay below the break. I took that to mean as the voice you are developing. If it's not then maybe she says otherwise later.
I did listen all the way through how to develop a female voice (Melanie Anne) and she said to speak as low as you can above the break... She says below the break is "male voice". And she demonstrates either starting high and lowering your voice down to the right place, or starting with a cartoon voice and drawing it back, which she demonstrates by relaxing and widening her throat, it sounds like.
But, I have already reversed something she said, so maybe I'm doing that here too.
Also, if the point is to avoid the break. Then there is the idea of not breaking.
I made different clips, that have no or much less of a break, and that don't go on to play my grating falsetto voice.
The idea is that when my voice approaches the break, I make the yawn or "duh" voice:

http://vocaroo.com/i/s1hQ2cwYsglzI can't speak in the passagio area, yet. But, it seems to me like with practice I should be able to speak fluidly. Together with shaping the throat to mimic a smaller resonating chamber, I think it means that you can choose the pitch that is appropriate anywhere from bass to whistle register.
