Before you actually do this, you might want to monitor the altitude output on your GPS while sitting still. I've watched various ones of mine and they float around by +/- 50 feet routinely. I can see it when I drive up over the causeway bridge (the highest point around), but I can be driving down the flat road and the altitude is floating up and down as if I were in rolling hills.
Maybe it works better in truly hilly or mountainous regions?
