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!
