Actually she's not a practitioner yet. She is still finishing up with some other modalities first. But I can say this.
The reason questions are asked is so that the practitioner can hone in on the right test windows..there are tons of test windows to chose from. As far as I understand there is no pre data inputed about the person being tested though. The machine tests blind. I will double check for you though. Good question.
I will look at the manual and I will ask some knowledgeable practitioners. Too bad these machines are so darn expensive. We should all be able to own them. The other big problem is that government/pharma are trying to have them outlawed soon along with other electromedical devices. Yikes.
