I hiked with a group that used 2 garmin GPS and they measured the distance as 9.? km's. My MMT measure 16 km's. http://www.mapmytracks.com/explore/activity/2241176

The official distance for the downward track for the above hike is 11,? km. Although I did a lot of extra km's going back and forth helping stragglers, I did definitely not do 22Km's http://www.mapmytracks.com/explore/activity/2242113

Is there a way I can calibrate the app?

Yesterday I did another hike - real total time was 3 hours, MMT indicates 1:17 and the distance also feels too long (http://www.mapmytracks.com/explore/activity/2260567#)

I like the way MMT works, but I need accuracy and confidence that I can trust the data!

Any suggestions?

I am on android and use a Sony C3 Model D2502 with Android 5.1.1

The issue here relates to the GPS hopping around when traveling at low speeds. You'll see from your GPS route that the trace is not very smooth. This is caused by the GPS accuracy. This can vary between different phones but the main cause is the low speed while walking.

We have this on the development agenda to improve how low speed activities record their trace and we hope to have this included in an update within the next few weeks.
