This comparison is not good at all since you're only considering one metric, maybe he's a 10x runner because he has better technique, recovers faster, gets less tired, etc.

It's like comparing developers by how fast they can type.

Yes, this is why I thought the idea of "of course there are 10x developers because there are 10x [other categories]" was not a very useful statement. There are many dimensions to this assertion. In what way is a 10x developer 10x? And furthermore, could it be that there is one single dimension of a certain workflow in which a developer judged not to be 10x is simply fumbling in the dark, only able to work by random trial and error, while the 10x developer has a clear view of? Take two developers with equal aptitude with creating efficient algorithms, fluency in a certain language, facility with dev tools used in that role, etc, but one has no clue about networking concepts. Given a task that involves networking, one may well appear to be 10x the developer, when in fact their actually just an infinitely superior network administrator.
