Ezt persze úgy kell értelmezni, hogy hibátlan leütések száma.
Hibás leütés esetén ha jól emlékszem az egész szó levonandó.

"Szakmai vizsgán az alapfokú gépírási sebessági követelmény... 170 leütés/perc, középfokú 230 leütés/perc." www.gepiras2000.hu/.../Gepiras_2000_felhasznal

Bocs, most látom, hogy angol válasz kell:

STROKES PER MINUTE 185

CPM: characters per minute
A gépírás sebességét a percenkénti szószámban szokták megadni, de itt valószínűleg nem erről van szó, mert a 185 szó/perc az szupergyors gépelés lenne, nem létezik, hogy iskolai követelmény lenne.
http://en.wikipedia.org/wiki/Words_per_minute

"A less common measure of the speed of a typist, CPM is used to identify the number of characters typed per minute. This is a common measurement for typing programs, or typing tutors, as it can give a more accurate measure of a person's typing speed without having to type for a prolonged period of time. The common conversion factor between WPM and CPM is 5. It is also used occasionally for associating the speed of a reader with the amount they have read. CPM has also been applied to 20th century printers, but modern faster printers more commonly use PPM (pages per minute)."

Van egy másik kifejezés, a Keystrokes Per Minute (KPM), de azt leginkább a 10-billentyűs numerikus billentyűzet használatával végzett adatbeviteli munkáknál használják.
Az első példa ugyan folyamatos szövegre használja, de valószínűleg hibásan.

"What is this?

TyperA is a Java program that tests your typing speed. You get randomly chosen words or sentences and try to type them as fast as possible. A game lasts for one or two minutes. The program counts letters of the correctly typed words and divides it by the test time. This will be your score, expressed in KPM, keystrokes per minute. "

"Good typists, especially those who are also excellent at 10-key typing, are often qualified for data entry positions. 10-key typing uses the 0-9 keys often found on the right side of a computer keyboard, also called the number keypad. Most companies that hire people for this work have requirements for Keystrokes Per Minute (KPM), with a high degree of accuracy. These numbers can vary from one business to another, but are based on individual keys rather than words. "
