Ive just done a 10km run, when downloaded onto the PC the data show 5.40min per km (don't laugh); giving 54.0 for the 10km. But 'actual time' shows 56.41. I did stop to walk a couple of times but paused the watch. Any ideas? A second point. On the display of split times there is often a a set of figures in orange at the bottom; what are these?
