Simple to find, go look at a decent size blockcache and the "00" directory has the most blocks, then the "01" directory has less, then less in "02" and so on.
It could be the random number generator, it may not be up to encryption standards. What does AES use?
It could be the random selection of blocks to XOR with.
It could be the way the program picks blocks to push. After long runs with no downloading the cache would tend to "skew" the way that pushes are picked.

Counting alls 170000+ blocks in my cache i could not find a relation between the first block hash byte and the number of blocks. The directory with the most blocks in my cache is "cf" not "00".
OFFs main "Random number generator" are the users! The files they store provide most of the entropy.
The remaining entropy (3 random blocks on startup, randomizer selection (not content!) is provided using rand().
