The difference between an untrained runner, a trained runner and n elite athlete are left completely unanalyzed. Given how seemingly varied for no apparent reason some of these points on the graph are and coming from an anecdotal perspective this analysis is not very useful, and probably even wrong.

Seemingly an elite athlete must have been tracked because almost nobody(considering the whole population) can run the given top-end pace for a sustained amount of time (More that 100metres).

I was hoping for more from the article, or at least that it was called 'calorically More efficient'.

It's not like the author says this:
