If you don't press space, you're violating the idea of words. If you press space, the sentence you've constructed in your head is broken. Either way, it slows me down and frustrates me too much to play :)
The original study used only a timer, and had the same frustration which you speak of here.
The text is appearing really slowly for me. Is there something that I'm missing? I have to keep waiting for it to catch up to me.
EDIT: I was using Firefox. In Chrome, it's completely different.

"This is infuriating"
So congratulations? These are both people that do extensive amounts of work on the computer but none of it involves copying quickly.
For me, I'm a bit curious why words per minute matters for people. It seems like the only time typing so quickly matters is when you are copying things down (written or spoken). Don't you think it is only a matter of time before no one will have to copy something down into text format manually ever again?
I have little knowledge about how the brain works when copying information but it seems that when someone is working hard to quickly copy something down they are not analyzing the meaning of the content nearly as well as if they were sitting and listening. It seems like time could be better spent.
I still think this is an interesting site. I would love to improve my typing accuracy.
That said, I do acknowledge that WPM is not necessarily the best gauge of efficiency. I'm a programmer, and I'm not sure exactly how WPM relates to my work (I'd be curious to see a study) since much of what I type is "nonsense" words to begin with, and WPM is largely a function of your ability to habitually reproduce the same character sets (aka, common words in your given language).
Once you get fast and accurate enough - you've built into yourself the buffer space to be able to spend time on understanding.
Plus its always a neat ability to have. Especially being accurate. Making spelling mistakes and having to press backspace is infuriating.
edit: ok, I was typing too fast to notice that it automatically moves on after some time.

Edit: ...and now I can reply. Go figure.
Please understand that I'm not trying to be difficult, but that this is how I normally type. I'm interested because I haven't found the best typing app yet. But for a typing test to be accurate for me, it has to conform to the way text (or my train of thought) normally works.
If so, I think that not correcting my typos is a habit I would prefer to avoid.
