Are perfect-reduplication and quasi-reduplication related?

[Koen G]

I'm not sure about how to compare reduplication and quasi-reduplication. Is it possible to quantify the average edit distance between a word and the next one? In that case you could compare it to a shuffled text. This would show whether the large amount of quasi-reduplication is just the result of overall small edit distance between words or not. 

Basically, is the amount of word pairs with edit distance = 1 equal in a shuffled text? If this is the case, then there is no mechanism guiding the phenomenon of quasy-reduplication. I know this is beside your actual question but it might be a first step...
