Thanks for posting the profiles. Looks like most profiles are pretty round and nice, which is a good thing. The less arrows and spikes the better quality of the groups and their placements.
As people might have noticed I tagged it as experimental, because I'm not 100% sure that all 155 questions are independent enough, especially since I made some very late additions of questions that haven't been in the quiz much before. However, I think that at most a few questions might be replaced or re-grouped.
