It was my own article so I will just repeat the information here.

I friend of mine recently wanted to get a benchmark on a popular
downhill run.  This particular run has been measured numerous times with
GPS and by paceing with a bicycle.  It's good for 30+ mph without
significant effort.   My friend went all out on his run but the GPS
measured a max speed of 17mph.

The most likely explanation is that the unit lost contact with the
satellites only recovered in time for the run out at the bottom.
