I concur. I've demonstrated that I'm a 10x+ full-stack programmer several times in my career, but I've met at least a few people who could bang out code better than me. I can design complicated systems with many moving parts to solve difficult business problems, and hand them off to someone else to manage with minimal maintenance. I've done it many times. However, I worked with one young guy who understood Ruby better at age 25 than I ever will. But then it came time to log into the server and do something, and he didn't even know how to open a terminal and SSH into the box! So, no, I don't believe a simple coding test will find people who are "10x" in software development. There's a lot more to it than just writing lines of code.
