Monster carrying capacity
A monster's carrying capacity is calculated based on its weight or size relative to a human. Specifically, it is determined by the following procedure:
where cwt is the monster's weight, if cwt is not 0. The weight of a human is 1450 for this calculation. If the monster is strong and weighs less than a human, then the monster's carrying capacity is set to 1000.
For a monster with a cwt of 0, its carrying capacity depends on its physical size:
where msize is 0 for tiny, 1 for small, 2 for medium, 3 for large, 4 for huge, and 7 for gigantic. Humans have medium (2) size.
Finally, if the monster is not strong, then its carrying capacity is divided by 2:
Note that despite the source code comment mentioning corpseless monsters, the formula based on monster size is only used for monsters with a cwt of 0. Thus, a corpseless lich, with medium (2) size and 1200 weight, has a carrying capacity of 413, not 500. A wraith, with medium size and 0 weight, has a carrying capacity of 500.
In effect, the carrying capacity of a non-zero-weight monster is if a monster is not strong, and if a monster is strong.
