OK, perhaps better is a settings option to set the GPS accuracy with a slider bar with +/- 30m, 10m, 5m, 1m (?) as "best" accuracy and then also a "live view" for the user to determine when to take the measurement.
Unfortunately, if a user sets the accuracy to 1 m and the phone never achieves it, then the setting is a little like false advertising. But we can put some text in there explaining what that is. I suspect that the live view will be the most useful after an accuracy of < 10 or 5m is selected.
