Interesting perspective... But I didn't understand the drastic drop after 18mm.[/quote]
Imagine a circle expanding from the middle. Up to 12mm radius it is complete. Between 12mm and 18mm the top and bottom of the circle are outside the frame so don't count. After 18mm, you also lose the sides of the circle and are left with only the corners.
