                         TYPING ACCURACY
                 Typing Accuracy is defined as the percentage of correct entries, out of the total entries typed. It can be:

                         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
