1. GPS technology has a working precision of about 3 meters / 10 ft. While generally, the coordinates are very accurate, there is dependence on which and how many satellites are being used during the time of the scan. This will create a slight variance from time to time, but should not dramatically affect the functionality of Runasset.

  2. For maximum accuracy, be sure your device is using full power and other GPS settings set to the most precise settings.
