It's not very complicated. Just try to invent blot that can increase and :>then magic word "asymptotics". Well, I found a blot that can increase, but not a thousand-fold... take a very large "sheet" of ink and punch holes in it, with diameter slightly less than 1/sqrt(2pi)... unless they are spaced too close together they will all be filled after one generation, while only the outer edge of the whole sheet will have started degrading... am I on the right track?
