Are perfect-reduplication and quasi-reduplication related?

[Koen G]

Thank you Marco, I like these kinds of tests since they bring us closer to the core of Voynichese issues.

I once tested whether reduplication impacts larger-window TTR by simply removing duplicated words within a short distance. Small-window TTR went way up while larger windows felt little effect. So as you say, reduplication (and even things like a.b.a patterns) are not enough to explain TTR differences.

Your experiment with shuffled texts might teach us more about the relation between TTR and reduplication.
