I think that typerace is funny but I did it three times and there are several thing that make it hard for me
1. Everything is English which is harder for me
2. Some texts have lots of , . ! ' or whatever and stuff like ' is actually harder to write on a Germany keyboard than on an English one

3. The texts are different (which is good so that you cannot just learn it) which makes it hard to compare as I noticed different difficulties (for the race its okay but for comparing typingspeed with other people who did other texts it's not)
I learned to write blind and I had about 80-100 letters a minute some years ago, no idea if it got faster or slower ... so ~1,5 keys pressed a second
