High delta, good connection

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?

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.
