Significant Change Map

At TingoFamily we have been doing some testing with the new Apple iOS4 Significant Change API. The following image is a map (slightly offset to protect the innocent) of position changes over the weekend:

The fact that the user in question never went west of the body of water in the center of the map leads me to wonder about the utility of the data from this API. I am going to try out doing a full GPS query when the app gets woken up on significant change to see if I can get better results.
