David, Perfect-hash schemes are often very useful for match-seeking. They are not, however, usable for bound-seeking--here specifically GLB-seeking--operations that evaluate a step function. Very few of the search arguments--STCKE/TOD-clock values--for which a bound is sought are even present in the table.
