In the last couple weeks my Sense has had issues with the GPS connecting, not connecting, not connected, taking forever to connect. It's worse when the activity is Walk but is also happening with Run. So last week I did a test. I did an out and back walk that I know to be 4 miles roundtrip - turn around at the 2 mile mark. I recorded the outbound separately from the return trip to see how it would measure it. It measured the outbound as 1.5 miles. But then measured the return at 2 miles. EXACT SAME ROUTE! Fix one thing and break 3 more things - that's what fitbit keeps doing. The core functionality should be accurately tracking distance. If it can't do that, it's time to move on to something that can. I'm over it.
