Indeed, that's the reasoning behind the proposed approach. We don't
want it to typically be changing constantly for an individual user.
Yes, a sequential run does introduce various problematic biases.

An IP-address based hack could work, but would need to take into
account dynamic IP addresses and such, without introducing strange new
biases of its own. We'll discuss a bit further - good ideas /
algorithms welcome. :-)
