It was indeed Battle Analysis. The reason we have an idea of the Black Mage's HP is due to a hacker in GMS soloing him (he got permanently banned not too long after though). The thing is, the battle analysis also records the damage used to break the Black Mage's white shields. I do keep track of Namu's wiki from time to time, but I've noticed some inaccuracies here and there; sometimes I would send an edit request to fix the mistake if I'm 100% sure about it.
