Watch The GPS Accuracy Plummet After Start/Stop and Auto-Lap
No, I wasn't driving during this, but had some free time while in a car and used my phone to videotape. I tried this multiple times. It always messed up after start. It was occasional after auto-lap. Accuracy goes to 250+ ft from < 20ft. No wonder I can't trust the distances.
