Winning a typing contest won’t change your life. Learning that practice actually works might.

What transfers is not the result, it is the proof of the mechanism. A small contest matters almost not at all by itself, and what it can show you is that deliberate repetition genuinely moves a number, which is a fact about how you work rather than about typing. Once you have watched practice function on something trivial, you can believe it about something that matters. That belief is the real prize.

So pick a small measurable thing and run the experiment on purpose. Record where you start, practise for three weeks, measure again. The evidence about yourself is the point, and you get to use it everywhere.
