Typing Accuracy: Why It Matters More Than Speed
How accuracy is measured and how to improve it.
Accuracy is measured per keystroke
Keystroke accuracy is the share of your keypresses that were correct on the first try: correct keystrokes divided by total keystrokes. This punishes a mistake even if you later fix it, which is realistic — the error still cost you time and rhythm.
Corrected vs uncorrected errors
There's a difference between a mistake you catch and fix and one that survives into your final text. We track both. Uncorrected errors are the more serious kind because they leave wrong text behind; corrected errors mostly cost time.
How to improve accuracy
Slow down until your errors nearly disappear, then hold that pace until it feels easy before speeding up. Identify the specific keys you miss and drill them. Keep your fingers on the home row so every reach starts from the same place, and don't look down — glancing at the keyboard breaks the feedback loop that builds precise muscle memory.
