Why this test matters
The 15-second test is best used as a daily streak builder. It's short enough that there's no excuse not to do it, long enough to catch whether your fingers are warmed up, and cheap enough psychologically that you can take it five times in a row without burning out. Don't take a 15-second score seriously as a benchmark — variance is too high. But for daily habit formation? It's the perfect entry point. Most typists who reach 100+ WPM started with a streak of short daily tests, not marathon practice sessions.
