Ways to test GPS

Had a good chance to put the Nuvi 765 to an unusual test on Saturday, it recorded the fastest speed I have ever had on a GPS , No... it was not in the Troopy, It recorded 190 Kph , I was in that little Jabiru 120 again , the flight was from the Ultralight strip near Noonamah to Batchelor Airstrip, the distance was 61.3 Klms, 31:19 mins, Av speed was 117 Kph , that included taxiing both ends, the recorded track looks good overlayed on Google Earth too.
