My feedback, for what it's worth, is that I clicked "try it out" and got 2 minutes into the white dot test before closing the tab. I really didn't feel engaged with it and even missed one of them because my eyes were wandering around the room thinking about other things. I suppose this is exactly the kind of thing that the tests can pick up, controlled for the various variables, but not if it's so tedious that I don't even finish the test. I'd be interested if you have the data on when people are closing tabs and to what extent I am an outlier. I felt like I was being patient lasting two (out of three) minutes, but perhaps I'm unusually low-attention spanned in this kind of task.
