It should be noted that, in order to extend the transition lengths, one would need to rerun the entire set of transitions from scratch which compounds the computational cost, not to mention the incovenience. This is the reason why we do not recommend starting with any smaller value of transition length in respective cases as only a small fraction of complexes are expected to meet the threshold criterion (see Discussion for details) using relatively smaller transition length; while for the rest it would amount to a waste of computational resources.
