Sound to me like "tacit knowledge" is simply a practical skill?

I mean, obviously you can explain many things to someone who can't replicate it "just in time", riding a bike is one of those examples.

Explain math, playing guitar, reading, or whatever perfectly to a person, they still have to practice to be able to do it.

The problem isn't the explanation, it's the difficulty of the skill to learn.

Don't know why we need a new word/phrase for it.
