CRT strokes per hour refers to the data entry keystrokes completed for 10-key insertion on a computer keypad. The average 10-key speed is around 8,000 keystrokes per hour, denoted by the letters KPH. Typically, an excellent 10-key speed is over 10,000 KPH with no errors.
Traditional CRT displays and computer keypads were used for keying in numbers during the early days of data entry work. Therefore, CRT strokes per hour is a term that may be used interchangeably with the term KPH.
It is important not to make errors in data entry work since accuracy is essential in keying in numbers for many tasks, such as creating financial reports or recording banking information. The time wasted making corrections can outweigh the benefit of quickly keying in numbers.
As a result, applicants are penalized for each error they make during a 10-key data entry test. Ten KPH are typically subtracted per mistake. Test takers are advised to correct any errors by using the backspace key instead of trying to beat the clock during a timed exam.
A keystroke entails typing a character on a keyboard. If a typist keys 6,000 keystrokes in 60 minutes, it equates to hitting 100 keys a minute.
