The study that defined the 10x engineer defined him as 10x as good as the worst engineer. If there is a 0.1x engineer, and a 1x engineer, that 1x engineer is the very definition of a 10x engineer.

I've long thought a 10x engineer is one with just the right amount of analysis paralysis - not too much or too little. It's not that they're 10x engineers, it's that everyone else is 0.1x due to a confluence of reasons. And the ones we call 0.1x are 0.01x.

There certainly are 10x engineers just that they get most of the x from turning down bad ideas and saving work.
