interesting... that calculator says I'm at 89.5%, and that 90% is world class... how is that possible? a 21 year old who runs a 14:30 is nearly world class? I wouldn't even qualify fir USnationals, or even NCAA D1 nationals.. how the heck am I at the top of "national class" and almost "world class"?
Now perhaps you will understand statistics better (not being sarcastic, just trying to help). You now understand just how rarefied, compared to the total population of runners, your time is. A 16:00 5K is way out on the upper tail of the bell curve.
In the grand scheme of things, including all runners everywhere, the difference between "local" class, "national" class, and world class is hard to measure compared to the average.
Or to put it another way: there are what, 10's of thousands of collegiate runners? And NCAA nationals gets about 20 for the 10K finals? That percentage is so low, just on a collegiate level, that a decrease of even 0.5% adds a LOT of runners.
