Seeing what you don't see?

Do you have blindsight? I have only 43%, which means that I have weaker blindsight.

The purpose is to make it so small, fast, and weak in contrast to the background that you can barely see it. When you do play the game, you're supposed to be unable to see the dot pop up in any of the four quadrants. Basically, you're guessing. It's more interesting whether you "guess" the right spot, because that's indicative of your blindsight, the ability to see unconsciously without the visual cortex.
