Error in Characters: Errors in characters calculate the percentage of characters typed incorrectly out of the
total number of characters typed.
Formula: Error (%)= (Characters with errors/ Total number of Characters ) × 100
Example: If you typed 500 characters and 20 were incorrect, your error rate would be (20/500) × 100=4%.
Error in Keystrokes: Errors in keystrokes measure the percentage of keystrokes that were incorrect out of
the total number of keystrokes made.
Formula: Error (%)= (Incorrect Keystrokes/ Total number of keystrokes ) × 100
Example: If you typed 400 keystrokes and 10 were incorrect, your error rate would be (10/400) × 100=2.5%.
Typing Rhythm
Typing rhythm describes the pattern and consistency in how someone types, encompassing both speed
and accuracy throughout a typing session. It reflects the fluidity and smoothness of keystrokes, transitions
between letters, words, and sentences, and overall typing pace. To control the constant typing speed,
the Slowdown indicator is used. The following points shows the different formula for the Slowdown
(percentage slowdowns) calculation:
Slowdown in Words: Slowdown in words measures the percentage of words that were typed with a delay
or slower than usual out of the total number of words typed.
Formula: Slowdown (%)= (Words with delay/ Total number of words ) × 100
Example: If you typed 100 words and 10 were slower than your usual speed, your slowdown rate would be
(10/100) × 100=10%.
Slowdown in Characters: Slowdown in characters calculates the percentage of characters that were
typed with a delay or slower than usual out of the total number of characters typed.
Formula: Slowdown (%)= (Characters with delay/ Total number of Characters ) × 100
Example: If you typed 500 characters and 25 were slower than your usual speed, your slowdown rate
would be (25/500) × 100=5%.
Slowdown in Keystrokes: Slowdown in keystrokes measures the percentage of keystrokes that were
delayed or slower than usual out of the total number of keystrokes made.
Formula: Slowdown (%)= (Keystroke delay/ Total number of keystrokes) × 100
Example: If you typed 400 keystrokes and 20 were slower than your usual speed, your slowdown rate
would be (20/400) × 100=5%.
