I see your point, and I'm not equipped to articulate the distinction. It is fuzzy. > Somebody serious about deliberate practice will spend a lot of time seeking “tacit knowledge.” Putting words in the author's mouth, he's saying that tacit knowledge is more important in areas where (i) execution isn't clearly prescribed; to (ii) perform at a high level. The author gets into how in certain fields, there's a "missing manual" and requires figuring it out yourself or undergoing an apprenticeship, prioritizing attainment of tacit knowledge. Leetcoding is a "missing manual" expertise path and doesn't converge, IMHO, like chess, violin, athletics, etc.
