Yes, Lang. The last one should be:
manō sankhāra → vaci sankhāra → kāya sankhāra → kāya kamma
Most of the time one consciously thinks about doing something before acting on it.
See, “Correct Meaning of Vacī Sankhāra“.
– Many people acquire more bad kamma with vaci sankhara (by consciously thinking about it for hours and hours) than with kaya sankhara. This is an important point.
