Percentile Performance Calculator

Use this page to convert times from one course to another and to graph the distribution of race times of high school runners. The chart's vertical axis is the normalized size of the population. For example, a value on the y axis of 0.04 means that 4% of the population has run the course in the time given by the line. Accuracy not guaranteed. For entertainment purposes only.
