However, professional typists type a lot faster on average -- upwards of 65 to 75 WPM. A good typing speed compared to the general population would be over 40 WPM, but compared to professionals it would be in the 75 WPM range.
This makes the number of words easy to calculate. Simply count all typed entries and divide by five to get the number of words typed. To give an example, if you typed 200 characters in 1 minute, your net wpm typing speed would be (200 characters / 5) / 1 min = 40 WPM. If you typed 200 characters in 30 seconds your net speed would be (200/5) / 0.5 = 80 WPM.
