So how would one determine if someone has 3 "top 1%" skill level (per the article)?
I suppose the answer is in 2nd half of the article?
Two types of more reasonably defined polymaths emerge - pick three skills and achieve a certain level of output in a reasonable time:
apprentice level 4% input, 64% output, 10 months
journeyman level 10% input, 80% output, 48 months.
thoughts??
