though.

H(GuardID | !GuardWeight - 1) for each guard, and then choosing the
closest guard to H(Seed | 0), the closest not-yet-chosen guard to H(Seed |
1), and so on.

guard-selection value (the H(Seed | i) above) change at pseudo-random
times as well.
âSimultaneous rational approximationâ of the selection-probability
distribution might make the performance of this technique somewhat less
horrific.
