I type 142 WPM on average. I think the lack of real English words is a structural flaw of this application.
To get really fast typing speed, you need to develop muscle memory for words not just letters. For example, when I type the word "complete" I don't think "c", "o", "m", etc. I literally just bolt out the word complete without even thinking about it. I don't believe there is any other way to be able to type more than 2 words per second.
This might be useful to get you to a certain level of moderate proficiency but I believe it will hurt you at higher levels.
