I'm replying to you rather than making another top level comment to prevent sprawl, but I'm adding a different way the effect changed for me. (I'll probably try yours later, when I'm done playing with it, lol) For me, holding a "picture" of what the picture is in my head and trying to heat map where I think my view is spotting the dots changed it from seeing about 4 (in a triangle or box) to about 6 (in weird squiggles). I think that actively trying to see it changes how my brain caches information as it moves the eyes' focus.
