I was writing something about my personal viewpoints of security needed 
in practice.
If you consider that bad/unjustified, forget what was written there in 
the present context.

On the other hand, note that my software is "indeed" offering the best 
to the users.
The result from the ENT test of the example run is excellent, isn't it? 
(Other schemes
certainly may achieve that as well, but that isn't the point here.)

To your last paragraprah, I have written in Prologue of the software 
that the it is a
[viable] alternative. I am claiming no more, nor less.
