Why tactical races aren't always won by those with the best PR at shorter distances.

Trying to predict finishing place using 1500 PRs gives a correlation coefficient of 0.681, with a significant p value of 0.015. For our purposes, you can think of the correlation coefficient as a number between -1 and 1, where 1 means the runners finish in exactly the order of their PRs, 0 means there's no connection between their PRs and finish places, and -1 means the runners with the slowest PRs finish best.
