If a gps signal stutters* or the trace wanders X amount. Once in a while that will fall within a segment. On a quick segment (of 3 mins for example) that'll be enough to mess it up to the point of it being useless. It'll have less impact overall on a slow segment (of 15 mins).
*quite often the timing sorts itself out after a while. So long as that goes on within the segment all is peachy.
^^ Yes, but percentages are balls.
