Some thoughts on "randomness".

Last few months worth of postings from mirror makers on the
list is enough to show that dreams of randomness are false.
For example al those w-strokes  wide and narrow, overhangs
big or small, inevitably end in advising something "accentuated".
Which is another word for non randomness.
Constant "going back to sphere", TDE's, central holes, zoning
and attempts to rectify it are witnessing that without clever thinking,
constant measurements and tests, all speaks against  hope that
randomness will automatically provide anything nearly acceptable
for ATM standards. Loosely used word "randomness" puts it in realm of urban 
legends,
similar to "Grind more worry less" proverb.
At the start of grinding, effects of factual non-randomness are invisible
because everything is rough. But at the final stages, the more we are
close to the ideal (sphere or anything else) the less we rely on randomness.
Just few strokes or few minutes of action before test, are allowed. If there 
will be
real randomness, than final actions could last minute or hundreds, result 
will be always the sphere.
But nobody believes in this. People are cautious and do few strokes and lot 
of
measurements to find out where to put further non-random efforts.

Perhaps I am all wrong, but in order to see how and why,  I will appreciated
to be straightened (or supported).

Vladimir.
