Mind Monitor

One data set looks normal while the other one where i was in high delta was reading i was in high delta even when i wasnt meditating what can cause bad readings. also is the highest value the brain wave most dominate at the time?

This means nothing without looking at the RAW EEG to determine data quality, sorry.
I can see J - Jaw Clench and BF - Bad Fit markers, so I will assume from this that data quality is very low and this is the reason for high Delta.

I believe it was because my forehead and the band were a little dirty I cleaned both and I was getting more accurate readings
