why is distance, elevation gain and loss so inaccurate?

I just came back from a 9 day backpack trip where I used my Garmin Forerunner 945 each day. My total mileage stats were 7.5% over the known distance, and my elevation gain/loss was about 22% under the known stats. Why is my Garmin so "off" and what do I need to do to get more accuracy?

Check the tracked routes and see where the positions are wrong. Maybe you started the activity too soon. Always wait for green GPS and then wait another 1-2 minutes before you press start to get more accurate position. Have a data screen with the map so you can check that the watch is located at the correct position before you start.

For altitude measurements make sure you calibrate the altimeter/barometer. You can either do it manually or automatically. If you know the altitude you should enter the correct altitude.

How do you know it's the Garmin that is off?
