High delta, good connection

[watermelonpumpkin]

I'm really confused - I've seen it mentioned so many times that high delta = bad or no connection but I've only received one bad fit in my graphs and 2 "J". It's only a small amount of time recorded because I wanted to re-test the connection etc, but all looks good.

Is this still a bad connection issue?

Thanks in advance!

Yes, still a bad connection issue. Click "All data points" then look at the RAW EEG again, I think you'll see it spiking quite a bit.
A big tell tale sign of a bad connection is where you see the Absolute waves flat lining. This means the connection was so bad that the algorithm stopped calculating the absolute waves.

Okay, thank you for your help!
