There is a newer speedtest, version 2:
http://schnell-schreiben.de/stv2/ although it delivers sometimes a wrong value of allegedly wrong written words.
@Jan: You may select your language, Italian is available
My records after several runs:
English:
You type
457 characters per minute
You have 85 correct words and
you have 1 wrong words
Who still says, that I'm slow? ;)
German:
Du schreibst
543 Zeichen pro Minute
Du hast 86 korrekt geschriebene Wörter und
Du hast 0 falsch geschriebene Wörter
German is more difficult, as we have nomen, which are written with capitals.
