Technically it's not a bug, but it's useless information.
When making a selection in the graph section, it displays average pace and average heart rate. So far still ok!
But, as you see in the example, it also displays the average time (0:19:24) and the average distance(3.55). However, I am interested in the total time in the selection and the totale distance in the selection.
For the time, it's easy enough to see in the example that I like to see 30:55-8:06 = 22:49 instead of (30:55+8:06)/2 = 19:30 (close to 19:24). For the distance, the calculation is similar.
