 If the minimum at the beginning of an era is deep, the next minima will not become shallower; in other words, the residue |α — β| at the moment of transition between Kasner epochs remains large.This assertion does not depend upon era length "k" because transitions between epochs are determined by the common rule also for long eras.The last oscillation amplitude of functions α or β in a given era is related to the amplitude of the first oscillation by the relationship |α"k"−1| = |α0| ("k" + "x") / (1 + "x").
