This ruleset assumes that as a predator's Capacity increases, so does their metabolism. If you want to assume that metabolism stays the same, try estimating the weight of each prey, then add half of each prey's weight to the predator's weight after digestion. This weight builds up much faster for large meals, so watch out!
