Do you see same patterns?

Just look at the plot that nablator referenced above. Let's take a random folio, e.g. f36r. You'll see that p and f occur many times in the first lines of the two paragraphs present in that folio (of which lines there are two). That's OK. What's not OK - or, let's say, what is strange though, is that they do not occur anywhere else.
