Case in point I have a friend who is a top 32 magic player in NA. She recently, not even a year ago recently, made it her goal to become a chess grandmaster and she's already 2000 ELO. You could argue that maybe some skills transfer but it's pretty shaky reasoning.

I know a software developer who could well be a concert pianist, for example. Ie., that pool of people who overlap, in that overlap, are probably extraordinarily talented.

Also it smells like a false metric. People who are in the 0.05% of excellence are probably still heavily invested in the thing they're excelling at.
