I did the test and came out 37% ahead. I was surprised.

That said, I often find myself fiddling with the cursor to mark my place when I'm reading something long, so the idea that extra indicators of place might help doesn't surprise me.

I feel better line spacing might also help - their test seemed to have the lines pretty tight together, although I'm not surprised a test would be designed to best showcase their software.
