[split] Percentage of word types that occur more than once

[Alin_J]

But then again, this is IMO nothing unusual for natural language texts.

Hmm, I would have rather thought that a ratio of 45% / 55% is the "normal case" in longer texts, but surely it depends strongly on the text genre and language.

Yeah, it does seem to vary a lot depending on both language and on type of work, e.g. fiction, encyclopedic, poetic etc.
