That's a bit curious... I'm missing something.  A B64 character set with 
lowercase and uppercase letters means you have two chances out of 64 to
get an "f/F" or 1 out of 32.  4 letters would be 32*32*32*32 or 1 per MB,
so you should have seen 3 (in half of a 6MB file) not 40.  I tried putting
a bunch of various mixed case (f-)words at different offsets within a file
and decoding it, but got back nothing interesting in ASCII.  So, uh, I
guess there's something else going on... like a word processor uses some
binary sequence that causes The Word to be generated an order of magnitude
more often than I would have expected.  Math Error?
