Why corrected errors still count
A backspace removes the character from the final text but not from the keystroke record. The accuracy score therefore reflects the mistakes you actually made, not only the mistakes you left visible.
Longer passages expose fatigue and careless habits that short bursts can hide. Type at a sustainable pace and watch how accuracy, errors, and WPM move together.

Use the first pass to establish your own error count. Repeat more slowly and compare which pace produces fewer errors before increasing speed.
Two minutes is short enough for a daily check and long enough to reveal rhythm breaks that appear only after the first minute.
Repeat a passage at a deliberately slower pace, then compare accumulated errors as well as WPM. A corrected mistake still contributes to the error count; a clean-looking final answer is not necessarily a mistake-free run.
Calculate WPM and accuracy from a worked correction example, or compare three scores from your own setup.
This tool does not set a universal pass mark. Compare your own errors under the same passage and duration, and choose a target suited to the task you need to perform.
Fatigue and attention drift reduce sustained speed. That is exactly what a longer test is designed to measure.
Accuracy is correct characters remaining divided by that count plus accumulated errors, multiplied by 100. For example, 480 remaining correct characters and 20 accumulated errors gives 96%. Correcting a mistake does not remove its error count.
WPM uses correct characters remaining divided by five and elapsed minutes. Raw WPM uses all inserted characters including mistakes and retyping. Backspace and modifier keys alone add no inserted characters; corrections still take time.
Two minutes gives you a longer sample than the one-minute test. It can reveal a change in pace within the session, but the result alone cannot identify fatigue or predict work performance.
