I am sorry, but I think I did not make myself clear: testing random numbers
post-processing with the statistical tools does NOT give any idea about the
entropy rate. Thus, all that was calculated is the proper implementation of
the post-processing operation and not the actual noise source.

What needs to happen is that we need access to raw, unconditioned data from
the noise source that is analyzed with the statistical methods.
