New mind brain map

I recently visited a neurofeedback center And had a qeeg Brain map. The system they used is New mind. The Brain map lasted around 10 minutes I was told to stay still and try to stare at an object they placed in front of me. Other than that they didn't give me any more instructions I was able to stay still but I did look around quite a bit and closed my eyes couple times as well. They didn't seem to comment on that. I was wondering if this is a effective/accurate brain map.
