The number of triphone decision tree leaf nodes is essentially not correlated with any of {total Frames,total Phones, error Phones, error Frames} per phone. Since the units are chosen to maximally cover the mistakes in the corpus, this might suggest that deepening the triphone DTs is not the same thing as coming up with these error-based units.
