Hi Priit,

yes, we know about this theory. It is usually applied to coastline

calculations

and basically says, "whatever you thought, it always turns out to be 50%

more!"

I cannot disprove your theory, because I donīt have the necessary

mathematical tools,

but; I can say the following:

1. This reasoning is the basis for fractal algorithms and leads into the

choas theory.

2. As my life is a chaos anyway, you canīt frighten me into thoughts of

rethinking it!

Just think, certain firms are using fractals as supports and others are

producing chaos!

(not advertising for anyone, no new product announcements, just

thoughts)
