I noticed that TTR (and the exponent of Heaps) decrease with N. The larger the section, the smaller the expected TTR. Therefore, before concluding, I believe it's worthwhile to separate size from behavior. And also observe the direction. If Recipes is one of the largest sections and still shows the greatest diversity, this is the opposite of what size predicts, a stronger anomaly rather than an artifact.
I think the ideal test would be to subsample each section to the same N (that of the smallest section), calculate the TTR in each subsample, repeat the process a few hundred times, and compare the averages with their dispersion. If Recipes (or the diversity of Stars, or the homogeneity of Herbal/Balneo) still stands out after that, it's a real section effect; if it disappears, it was due to length.
