did some quick math;
at 100% hunger rate, you're eating roughly 5-6 times a day, while active.
at 75%, its roughly 3 times a day,
50%, is 1.5 times,
and oddly, 25% is 0.3 times.
('a day' is a VS day, not real world time. the reason i calculated this, is because i wanted to figure out which hunger rate setting would have my character, while active, eating fairly regularly, without going overboard on gorging myself. (it doesn't really make sense to go from full to starving 6 times in a day while active, at least to me.))
only posting because i figure someone else might wander in here and wonder how many 'meals' your character eats per day, depending on hunger rate.
