Let's assume that there are 800 kids per school and 10 schools = 8000/2 = 4000 boys. 500 self select to run track in the conference and the distance runners average 40 MPW and none break 5 minutes. You can bump them up to 50 to get a few guys out of 4000 to break 5 but that puts the average guys out of the 4000 at more like 7-8 minutes.
Big problems with that analysis:
1. It's entirely based on assumptions and hand-waving.
2. The other 3,500 boys are also humans that are very similar to the 500 self-selected runners.
3. Do you really think that there is a population of 500 male distance runners that run 40 mpw where zero of them can run a mile in less than 5 minutes?
(There are certainly regions and states where nutrition and obesity are major problems and the normalization of poor fitness contributes to lower standards for health and fitness because everyone just observes the behavior of those around them. Let's not think of these humans as a representation of normal or average. Many of those exact same people would be much more fit if they just lived in a different location.)
