<P> Stenotype keyboards enable the trained user to input text as fast as 225 wpm or faster at very high accuracy for an extended period of time, which is sufficient for real - time activities such as court reporting or closed captioning . While dropout rates are very high--in some cases, only 10% or even less graduate--stenotype students are usually able to reach speeds of 100--120 wpm within six months, which is faster than most alphanumeric typists . Guinness World Records gives 360 wpm with 97.23% accuracy as the highest achieved speed using a stenotype . </P> <P> The numeric entry or 10 key speed is a measure of one's ability to manipulate the numeric keypad found on most modern separate computer keyboards . It is used to measure speed for jobs such as data entry of number information on items such as remittance advice, bills, or checks, as deposited to lockboxes .

Many jobs require a certain KPH, often 8,000 or 10,000 . </P> <P> For an adult population (age range 18--64) the average speed of copying is 68 letters per minute (approximately 13 wpm), with the range from a minimum of 26 to a maximum of 113 letters per minute (approximately 5 to 20 wpm). </P> <P> A study of police interview records showed that the highest speed fell in the range 120--155 characters per minute, the highest possible limit being 190 characters per minute . </P>
