Thank you for contacting TypingMaster. I regret that we are not able to write to you in Spanish but you can continue using Spanish in any further correspondence.

TypingMaster follows international industrial standards to count typing speed. For written English, the commonly accepted standard is a 5-stroke standard word, including spaces and punctuation marks. This is the default setting in all English language TypingMaster products. 

In result calculation this means that 5 keystrokes make one word and 5 keystrokes are deducted for each mistyped word. If needed, the word length can be changed on the Settings tab (>Settings>Study settings>Word length).

Gross typing speed is calculated as follows:
1) Total keystrokes are divided by duration, which gives gross speed in keystrokes per minute
2) Gross speed in KPM is divided by the standard word length to get typing speed in WPM.

Accuracy percentage is calculated using the standard word length. Gross keystrokes is the total number of characters typed. Error penalty is the number of words typed incorrectly times the word length. Net keystrokes equals gross keystrokes minus error penalty. The rate of net keystrokes to gross keystrokes gives accuracy percentage.

Net typing speed is the typing speed with errors counted in the result and is calculated like this:
1) Total keystrokes minus the number of incorrect words times word length, to get the total net keystrokes for the whole test duration. 
2) Total net keystrokes is divided by the test duration to get net typing speed in keystrokes per minute. This is divided by the standard word length to get net typing speed in words per minute.

Example of result calculation:

A user completes a typing test with 1750 keystrokes in 5 minutes and 5 incorrectly typed words. The results are:
- 1750 gross keystrokes, 25 error penalty (5 mistakes * word length 5), 1725 net keystrokes
- Gross typing speed is 70 WPM (350 KPM)
- Net typing speed is 69 WPM (345 KPM)
- Accuracy is 99% (1725/1750*100%)
