Sounds like your doing most of what the system has to say.
The first thing I note missing is your purpose.
The next thing I wonder about is the number of questions. I usually only have 3 or 4 per pass. Too many and the mind get scattered.
I don't use mindmaps, but I always imaged they were to facilitate the activation. They are not meant to be an end product. My concern is you are trying to duplicate your experience with mindmaps, rather than use them to explore ideas / connections / thoughts that enter into your conscious mind.
I remember seeing a post by Pete, saying that sometimes he gets to something like his 6 or 7'th activation pass and feels he know nothing, then on the next pass it all falls together. I guess on those big learning curves you have to add many layers before it you can see over the wall.
I hope that's given you something useful to chew on. Alexk will have a thing or two to add, I'm sure.
Sending love,
