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.
