Speaking of which:

>>> from itertools import product
>>> len(set(map(hash, product([0.5, 0.25], repeat=20))))
32

32 hash codes out of 1048576 distinct two-tuples isn't exactly confidence-inspiring either ;-)  No scheme that only "propagates to the left" is going to help that much, because the variation in those hashes is all in the high-order bits.
