Thank you for your replies.
To answer the question posted by amused to breath :
When I started with muse, my scores were lower then now, between 50-70%. At one point I used Internasel Low Light Laser Theraphy device, and since then all my scores where between 80-98%. The photos are showing the differnce that I had since using the lllt, and I had done about 50 sessions afterwards, almost all of them where without reaching the active zone, with the same pattern as seen in the picture - my mind did not move up and down quite as often.
I would say that during the meditation I had some level of anxious thoughts, which I could feel in my body as tension, most of them are verbal.
I would say that during calibration my mind is space verbal and visual sometime auditory, depends on the question asked during calibration. I was skipping meditation for a few days, and on the last attempt, with the update, I got a score of 78%. I never thought I will be happy to get a lower score.
When I sat down to meditate I did feel body tension and then tension thoughts would come up. It was surreal to listen to my thoughts talking rapidly while I can hear the birds in the background.
I will try to do short meditation and see how it will affect the scores.
I will try breathing 5 minutes before and I'll see how it will affect the session.
I have also attached a photo from my last session yesterday.
