Some tacit knowledge maybe is impossible to document, but in a lot of circles there is a distinct lack of ability by those who are skilled in some activity to describe how they do things. There is often a split between those who can execute at a world-class level, and those who aren't as good but can teach others effectively. I've seen this dynamic play out in competitive videogames, figure skating, musicianship, etc. Take figure skating for example. I was being taught how to do a basic two foot spin by someone I know who is/was a competitive figure skater. Not a complicated move. They completely failed to explain to me a critical part of how to do the spin effectively (namely, where on my blades I should keep my balance and how I should angle them). So did several instructors leading classes on figure skating. I floundered for a while until one day I managed to figure it out by random chance. I was quite annoyed, because to me it is a perfectly explainable thing that everyone was apparently either just figuring out through trial and error or just didn't think was worth explaining. But these kinds of pedagogical "blind spots" pervade nearly all human fields of study.
