Subject: To build up speed and accuracy
There are a few games like Snow Typer, Type Fast, Fast Typer 2 and many more available in Rapid
Typing software that can help you build up speed and accuracy.
TYPING ACCURACY
Typing accuracy is defined as the percentage of correct entries, out of the total entries typed. It can be:
Example
In Terms of Typing Accuracy
Supposition Net Speed
Accuracy % = 100% - ((Words with A person typed 50 words Accuracy = 100 - ((6 * 100/50)
Word errors × 100%) / Total number of per 2 mins. with errors in 6 => 88%
words) words.
Accuracy % = 100% - ((Characters A person typed 250 Accuracy = 100 - ((30 * 100/250)
Characters with errors * 100%) / Total number of characters per 2 mins. with => 88%
characters) errors in 30 characters.
Accuracy % = 100% - ((keystrokes A person typed 200 Accuracy = 100 - ((40 * 100/200)
with errors * 100%) / Total number of keystrokes per 2 mins. with
Keystrokes => 80%
keystrokes) errors in 40 keystrokes.
TYPING RHYTHM
The Typing Rhythm means typing a character (keystroke) at equal intervals using the touch typing method. To control
the constant typing speed, the Slowdown indicator, in terms of percentage is used as given below:
Example
In Terms of Slowdown Formula
Supposition Slowdown
Slowdown % = (words with delay * A person typed 60 words Slowdown = (12 * 100) / 60
Word 100%)/ Total number of words per 2 mins. with delay in 12 => 20 %
words.
Slowdown % = (characters with delay A person typed 250 Slowdown = (20 * 100) /
Characters * 100%) / Total number of characters characters per 2 mins. with 250
delay in 20 characters.
=> 8 %
Slowdown % = (keystroke delay * A person typed 200 Slowdown = (40 * 100) /
Keystrokes 100%) / Total number of keystrokes keystrokes per 2 mins. with 200
delay in 16 keystrokes. => 8 %
