You are right, my ADEV plots are junk.  Removed.

It was the 24 hour scatter plots that I wanted you to look at.
Hard to argue with lat/lon data as reported by the device.

You can also checkout the TDOPs which are better on the MAX-M8N

Hard for me to accept your relative opinion of two devices when you have
never played with one of them.  Whatever my techniques may be, I have
side-by-side concurrent data for many GPS.  Hopefully any systematic errors
cancel out in the comparisons.

And anyone can run, maybe even improve, the FOSS programs I'm using for
comparison as well.  

But I agree, moving off topic for time-nuts.
