One helper technique that may turn useful is that function words, as such, can be expected to be distributed more or less evenly across the corpus, unless, of course, certain parts of the corpus are comprised of special patterns, such as numbered/unnumbered lists or labeled diagrams, in which cases there is no much room for function words to introduce themselves.
The count per folio, of course, cannot be a reliable measure here, because folios contain different number of vords. Some sliding window should be introduced - say, 1000 vords.
