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

[ReneZ]

I will be curious to hear what you find out.

Just a small collection of thoughts from my side...

I had always understood that the main 'mode' of self-citation would be from one source to one target, but I guess that there could be a combination of modes as well.

I have often wondered about the initialisation method. After all, the self-citation explains (in a way) how to set up the 'next' word from a previous section, but I never saw anything about how to start. 
Can one detect how many words are needed for the initialisation?
Only once? Once per page? Once per paragraph?

Another thing I have been curious about is how the most frequent words come about.
Are these part of the initialisation, or are they always appearing as a result of modification of previous words? So far, I have not been able to find a good answer, but your experimentation might...
