"Here is a study I did to show just how much Dvorak is better. While not a
formal study, it is a good demonstration, easily duplicated at home or for
a science fair project.

I also found a Dvorak advantage of 35 - 50% when typing samples of not only
English, but also limited samples of German, Portuguese, and Spanish."
