Discussion: More linear split difference

That makes the graph look a lot more reasonable. I probably did well on the way to 9 and you acknowledged doing poorly which is reflected in the graph. Otherwise, my pace was nearly linearly slower than yours.

Which means we were both folding up pretty badly in the heat. I know I could hardly run to 10 (in fact, I couldn't run up the hill to the control and it's not very steep). Felt a bit better to 11 (duh, it's downhill), but running the powerline out of 11 I felt like I wasn't moving at all.
