* Mussaf is always recited back-to-back with shacharis, and inserted before the end-of-shacharis עָלֵינוּ and psalm of the day; it does not add additional kaddishes to the service. Besides, after the sheloshim I determined to reclaim some of my time by reciting a halachically minimal bare-bones service in the morning from Monday to Friday and then leaving shul after בָּרְכוּ; by chosing not to count mussaf separately it means I don't count the kaddishes after עָלֵינוּ on the times rosh chodesh fell on a non-Sunday weekday as missed services.
† I didn't try and get there for the kaddishes before פְּסוּקֵי דְזִמְרָה because I knew they wouldn't have a minyan; I assumed I'd be able to say kaddish later in the service, like on any other day of the year. I was surprised to discover those were in fact the only mourner's kaddish and kaddish derabbanan in the entire day (aside from those the previous evening).
