Need advice for testing of hypotheses related to the self-citation method

But the "mutation" part of the SCM would require generating several coin tosses, with non-uniform probabilities, at each word.  And these probabilities would have to be finely tuned in order to generate the proper Zipf plot and other "natural" properties. 

Well said, I wholly agree with this.

Fully agreed too. 
Beside the "natural" properties there is the need to preserve the "slot table" properties.
