This post is in response to a Discord question, "What do the stat numbers mean, exactly?" I'll illustrate it using the kinds of people who'd have those stats. This only reflects individual ratings, not ratings that include advisors or outside assets. As time goes on and technology and knowledge advance, this scale may be subject to inflation.
~5: A normal person with a normal amount of ability.
~10: A trained professional or a very talented amateur.
~15: An experienced expert in their field or a world-class talent.
~20+: The top handful of people living in the world; only possible with both substantial talent and skill.
