Does having 9 big bolded points unduly influence human play?

To mark the points 4-4, 4-10, 4-16, 10-4, 10-10, 10-16, 16-4, 16-10, and 16-16, I prefer emphasis lines or flower dots. To me these stand out more.

Q is in a remarkable position.

I also does the trick of 'disappearing into plain sight' on Western go coordinates-nine times to be exact! It's true after all that ego and igo don't go together. It does seem though that at three-three you'd interpret it stand for territory, and at five-five you'd likely see it as enclosing all corner moves. So I doubt it would change too much. . .

But as mentioned above they do help counting points and coordinates, for me at least, in easy 5 and seven chunks.
