Net Words Per Minute (Net WPM)
Net WPM = max(0, ((Total Characters - (Uncorrected Errors × 5)) / 5) / Time in Minutes)
Each uncorrected error is penalized by 5 characters (1 standard word). If errors exceed typed output, Net WPM is bounded at zero.
Typing Accuracy Percentage
Accuracy % = ((Total Characters - Errors) / Total Characters) × 100
Measures what portion of your physical input consisted of correct characters.
