There is currently a bit of a competition going on at http://www.donationc...6;topicseen#msg21696
to see who can type fastest but one thing I notice is that people's speed is not reduced for errors.
Can I make two possible suggestions (both of which would probably mean making the test typing window a bit larger): either
1) force people to edit the text they have typed until it is 100% accurate before the test is complete (this means that the test would run for 1 or 2 minutes as it does now but after the time no new words would be given but the clock would not stop until the test is 100% accurate), or
2) deduct all letters in all words typed inaccurately, so for example if someone types "bit" instead of "bite" they lose 4 letters from their total letters typed.
Either of these would encourage accuracy and so there would be no benefit for typing fast but with little accuracy.
