Can we define what "better" is? Before we can develop a test to determine
whether a larger hamming distance is better, what are we trying to achieve? Are
we trying to spread the positions out more evenly over the hash table? Or is our
objective to have fewer full 64-bit hash key collisions? Or something else? I've
read these "larger hamming distance is better" threads in the past, but I never
really thought about what "better" meant :)
