 However, the natural variable for describing the time course of this evolution is not the world time "t", but its logarithm, ln "t", by which the whole process of reaching the singularity is extended to −∞.According to , one of the functions "a", "b", "c", that passes through a maximum during a transition between Kasner epochs, at the peak of its maximum is
where it is supposed that "a"max is large compared to "b"0 and "c"0; in 
"u" is the value of the parameter in the Kasner epoch before transition.It can be seen from here that the peaks of consecutive maxima during each era are gradually lowered.
