What exactly do you mean by "10x doctor"?

Some surgeons have a 10x higher 'revision rate' than others, and from what I understand, that may be an understatement. Many of the statistics which would indicate the ones to avoid are not tracked, precisely because the doctors do not want them tracked.

You'll have to ask the OP what they meant by 10x. I assume they meant it in the programmer/hacker sense of producing more work in the same amount of time than their peers or being a 'rockstar'
