Also, about your GPS distances, no GPS can get you within 5 feet of your current location. In ideal conditions in North America your best GPS performance will be within a 10 foot radius of where you actually are, but most conditions are not ideal, so your "fix" is more likely to be within 20 or 30 feet at each point, or worse, and your gps-measured distance between two points could easily be inaccurate by 50 feet or more. Or it could be right on. Hard to say, but it's preferable to use a more reliable tool than GPS for measuring distances in feet.
Just going off what the app info told me. Could have been a lie
