The Science of Typing Accuracy
Why accuracy beats speed
Speed means absolutely nothing without precision. Every time you make a mistake, you incur a massive triple penalty: time lost recognizing the error, time lost pressing backspace, and time lost re-typing the correct character. High accuracy naturally translates to higher overall WPM.
Score = ((Total - Errors) / Total) × 100
Professional Thresholds
In coding, legal transcription, or medical data entry, an accuracy rate below 95% is often considered completely unacceptable. Professionals aim for a strict minimum of 98% to 100% to avoid catastrophic database corruption. If your accuracy is low, slow down your gross speed until you can type entirely error-free.
