I did not yet list the percentages of chedy and Shedy occurences for the different sections.
They are:

              chedy   shedy
              -----   -----
Herbal B:     1.933   1.132
Biological:   2.979   3.485
Cosmo:        1.155   0.880
Stars (all):  1.732   1.048
Stars-Bio:    1.984   1.297
Stars (rest): 1.355   0.677

Total:        2.092   1.780

This shows that there is a general trend, but still significant variability between the different sections.
It is mainly in the Biological section that there is also an internal correlation.
I wonder if this could be related to the hypothesis that this quire is a mixture of two original quires. There has been quite some speculation about that
