Paul, I agree. I have 30 days of Adafruit data; the position is never quite static, bounces around over a couple of meters as one would expect for a receiver in 3D mode. Send me email off-list for details about lat/lon/alt RMS deviation and scatter plots. On the other hand, I have a second "identical" Adafruit receiver with distinctly different deviation patterns. I'm working through that mystery now. Nothing with this hobby ever ends up being a simple quick test.
