Log frequency of TD used to define the observation sequence.
Logarithms of actual frequencies of TD length were plotted against TD lengths and approximated to a broken-stick curve. Black dots represent the group with shorter TD lengths (<16.3 min) and grey dots represent the group with longer TD lengths (>16.3 min).
