Because of the set times the tracker transmits, the blue blobs do not always accurately reflect my stopping points. Sometimes transmissions occur while I am cycling, so they simply represent a point along my route. Sometimes a destination is not logged at all, due to the tracker’s failure to transmit without a clear view of the sky. So, while the yellow line is a precise representation of my route overall, the blobs are an unreliable log of my destinations along the way.
