Bad Elf / MotionX technical notes

I got a Bad Elf GPS for my iPhone. Some notes on using it with MotionX to record tracks:

I’ve been meaning to measure Bad Elf + GPS when the phone isn’t moving. My first attempt recorded no track, I think because it was clever enough to not record when not moving. Need to investigate Settings / Global: Accelerometrics Assisted GPS, Accuracy Filter.
