The same calculation may be applied to other creatures, and the same logic applies for them. Although this wiki will provide already calculated limb health values for all creatures in the game, as a courtesy and time-saving measure, if you wanted to create new types of creature and needed to assign limb health values, this is the method used to do so.
It's not normally possible to change the max HP of a creature's limbs, though it is possible to have a multiplier to one's base limb health value during [[character creation]] and start with more (or less!) limb health than would be normal for your species. For an already existing character, the only way to increase limb max HP is to perform limb training at a [[Dojo]]. The max limb HP gained there acts as an effect and does not change base limb health value (and therefore does not change [[Daily Reset]] values).
